Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.

Best practice is to not mix lseek/read with fseek/fread on the same
underlying file descriptor, as not all stdio implementations will cope.
Since the plugin uses lseek/read while bfd uses fseek/fread this patch
reopens the file for exclusive use by the plugin rather than trying to
restore the file descriptor. That allows the plugin to read the file
after plugin_call_claim_file too.

Since symbols created by HIDDEN and PROVIDE_HIDDEN assignments in

set eh->local_ref to 1 in _bfd_x86_elf_link_symbol_references_local.

Sections may well belong in multiple segments. The testcase in the PR
saw an allocated section being assigned to an ABIFLAGS segment, then
not being assigned to a LOAD segment because it had already been
handled. To fix that particular problem this patch sets and tests
segment_mark only for LOAD segments. I kept the segment_mark test for
LOAD segments because I think there may otherwise be a problem with
zero size sections.
A few other problems showed up with the testcase. Some targets align
.dynamic, resulting in the test failing with "section .dynamic lma
0x800000c0 adjusted to 0x800000cc" and similar messages. I've tried
to handle that with some more hacks to the segment lma, which do the
right thing for the testcase, but may well fail in other situations.
I've also removed the tests of segment lma (p_paddr) and code involved
in deciding that an adjusted segment no longer covers the file or
program headers. Those test can't be correct in the face of objcopy
--change-section-lma. It may be necessary to reinstate the tests but
do them modulo page size, but we'll see how this goes.

My original implementation for LDI32 pseudo does not conform to
the TI ABI. I wrongly documented my TI PRU ELF object files inspection,
which got propagated into my binutils implementation.
Issue was exposed when running the GCC ABI testsuite against TI toolchain.
According to TI ABI, LDI32 must use first LDI instruction to load
the MSB 16bits, and second LDI instruction for the LSB 16bits.
This patch will break binary compatibility with previously released
binutils versions for PRU. Still, I think it is better to fix
binutils to conform to the chip vendor ABI.

The _gp_disp is a magic symbol, always implicitly defined by the linker.
It does not make a sense to write it into symbol tables for output files.
Moreover, now if the linker gets a version script, the _gp_disp symbol
gets zero version definition index. The zero index means[1]:
"The symbol is local, not available outside the object."
But the _gp_disp symbol has GLOBAL binding. That confuses some tools
like for example the LLD linker when they get such files as inputs.
This patch fixes the problem - it prevents writing the _gp_disp symbol
in regular and dynamic symbol tables.
This was tested by running LD test suite on a mipsel-linux board.

Implement a more complex way of selecting targets to include or exclude
with `run_dump_test' cases, by extending the syntax for the `target',
`not-target', `skip' and `not-skip' options (with the binutils and GAS
test suites) and the `target', `alltargets' and `notarget' options (with
the LD test suite) to also accept a name of a TCL procedure instead of a
target triplet glob matching expression. The result, 1 or 0, of the
procedure determines whether the test is to be run or not. This mimics
and expands `dg-require-effective-target' from the GCC test suite.
Names of TCL procedures are supplied in square brackets `[]' as with TCL
procedure calls, observing that target triplet glob matching expressions
do not normally start and end with matching square brackets both at a
time. Arguments for procedures are allowed if required.
Having a way to specify a complex condition for a `run_dump_test' case
to run has the advantage of keeping it local within the test case itself
where tool options related to the check might be also present, removing
the need to wrap `run_dump_test' calls into an `if' block whose only
reason is to do a feature check, and ultimately lets one have the test
reported as UNSUPPORTED automagically if required (not currently
supported by the `run_dump_test' options used for LD).

Define and handle TLS relocations for FDPIC in BFD and gas.
In gas, the new relocations are rejected if the --fdpic option was not
specified.
We also define the __tdata_start symbol to mark the start of the
.tdata section. This allows FDPIC static binaries to find the start of
.tdata section, since phdr->p_vaddr of TLS segment is not a valid
value for FDPIC.

gcc configured using --with-ld always uses that particular version of
ld if it exists. This patch adds a check that the ld version reported
directly from ld-new matches that reported via gcc. I chose to
compare the ld --version output rather than a more strict test (for
example by gcc --print-prog-name=ld), because the version test allows
a user to run the ld testsuite after installing a new ld (in the place
expected by gcc).
