3e97ba7d58 ld: Fix several 32-bit SPARC plugin tests 
Several ld plugin tests currently FAIL on 32-bit Solaris/SPARC:

FAIL: load plugin with source
FAIL: plugin claimfile lost symbol with source
FAIL: plugin claimfile replace symbol with source
FAIL: plugin claimfile resolve symbol with source
FAIL: plugin claimfile replace file with source
FAIL: plugin set symbol visibility with source
FAIL: plugin ignore lib with source
FAIL: plugin claimfile replace lib with source
FAIL: plugin 2 with source lib
FAIL: load plugin 2 with source
FAIL: load plugin 2 with source and -r
FAIL: plugin 3 with source lib
FAIL: load plugin 3 with source
FAIL: load plugin 3 with source and -r
FAIL: PR ld/20070

all of them in the same way:

./ld-new: BFD (GNU Binutils) 2.34.50.20200328 internal error, aborting at /vol/src/gnu/binutils/hg/master/git/bfd/elf32-sparc.c:154 in sparc_final_write_processing

This happens when bfd_get_mach returns 0 when abfd refers to a source
file:

$11 = {
  filename = 0x28c358 "/vol/src/gnu/binutils/hg/master/local/ld/testsuite/ld-plugin/func.c (symbol from plugin)", xvec = 0x24ed6c <sparc_elf32_sol2_vec>,
[...]

While I could find no specification what abfd's are allowed/expected in
*_final_write_processing, I could find no other target that behaved the
same.  And indeed ignoring the 0 case fixes the failures.  The code now
errors for other values.  64-bit SPARC is not affected because it doesn't
have a specific implementation of elf_backend_final_write_processing.

Tested on sparc-sun-solaris2.11.

06f44071cc ELF final_write_processing 
Move setting of OSABI to final_write_processing, after symbols are
written.  This allows OSABI to be set based on symbols actually
written to the output rather than assuming input symbols will be
output.

Corrects object files such as the one generated on powerpc64le-linux
by ld-powerpc/pr23927.s which has a local STT_GNU_IFUNC symbol but
prior to this patch the file was marked ELFOSABI_NONE.

the problems.

5c3261b0e8 ELF: Call check_relocs after opening all inputs 
For all ELF targers, call check_relocs after opening all inputs and
garbage collection.  Since the symbol resolution is known, check_relocs
can be simplified.  Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.

Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.

ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.

Tested natively without regressions on i686, x86-64 and x32.  Tested
cross binutils on x86-64 without regressions for aarch64-linux,

a2f63b2e7a ELF/BFD,GDB: Handle both variants of the 32-bit Linux core PRPSINFO note 
Fix commit 70a38d42c5 ("New entry points for writing Linux NT_PRPSINFO
notes."), <https://sourceware.org/ml/binutils/2013-02/msg00023.html>,
and commit b3ac9c7756 ("Put more info in NT_PRPSINFO Linux notes"),
<https://sourceware.org/ml/binutils/2013-02/msg00024.html>, and handle
both variants of the 32-bit Linux core PRPSINFO note across all targets.

The 32-bit Linux core PRPSINFO note matches the 32-bit kernel structure,
defined as follows:

(gdb) ptype struct elf_prpsinfo
type = struct elf_prpsinfo {
    char pr_state;
    char pr_sname;
    char pr_zomb;
    char pr_nice;
    unsigned long pr_flag;
    __kernel_uid_t pr_uid;
    __kernel_gid_t pr_gid;
    pid_t pr_pid;
    pid_t pr_ppid;
    pid_t pr_pgrp;
    pid_t pr_sid;
    char pr_fname[16];
    char pr_psargs[80];
}
(gdb)

where the individual data types of most members are the same across all
32-bit Linux ports, with the exception of `__kernel_uid_t' and
`__kernel_gid_t'.  These are defined in <asm-generic/posix_types.h> as
32-bit `unsigned int' by default, however overridden as 16-bit `unsigned
short' in port-specific <asm/posix_types.h> for a few targets, mostly
earlier ports of Linux, specifically: ARM, CRIS, FR-V, M32R, m68k,
MN10300/AM33, s390, SuperH, SPARC and i386.

The default is the same as the PowerPC variant already handled, as from
the commits referred.  Make the special PowerPC case generic then,
removing the GDB part, and provide a backend flag to switch between the
two cases possible, with the 32-bit one being the default and the 16-bit
one explicitly selected.  Set the flag in the target backends affected.

5474d94f03 dynrelro section for read-only dynamic symbols copied into executable 
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

50e03d47b7 Pass link_info to _bfd_merge_private_bfd_data 
Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker
callbacks, eg. einfo for printing errors.  I was going to use einfo
for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.

4f26fb3a1b bfd,opcodes: sparc: new opcode v9{c,d,e,v,m} architectures and bfd machine numbers. 
This patch adds support for the opcode architectures
SPARC_OPCODE_ARCH_V9{C,D,E,V,M} and its associated BFD machine numbers
bfd_mach_sparc_v9{c,d,e,v,m} and bfd_mach_sparc_v8plus{c,d,e,v,m}.

Note that for arches up to v9b (UltraSPARC III), the detection of the
BFD machine type was based on the bits in the e_machine field of the ELF
header.  However, there are no more available bits in that field, so
this patch takes the approach of using the hardware capabilities stored
in the object attributes HWCAPS/HWCAPS2 in order to characterize the
machine the object was built for.

13a2df29c9 Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbols 
Since the backend elf_add_symbol_hook isn't called on local symbols,
the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols.
This patch changes the x86 backends to set has_gnu_symbols if there are
relocations against IFUNC symbols.  Other backends with IFUNC support
may need a similar change.

This patch also changes the type of has_gnu_symbols from bfd_boolean to
enum elf_gnu_symbols.

caa4096e84 Don't call bfd_link_hash_table_free 
Freeing the linker hash table is a royal pain.  It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table.  It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047).  Clearly the only place it can be freed
is actually in bfd_close.  This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.
