Fix commit d664fd41e1 ("Ignore dynamic references on forced local
symbols") and use alternative test actions and match patterns to
correctly handle messages like:
.../ld/ld-new: Removing unused section '.reginfo' in file 'tmpdir/pr22649-2b.o'
or:
.../ld/ld-new: Removing unused section '.MIPS.options' in file 'tmpdir/pr22649-2b.o'
produced by LD on MIPS targets, removing:
FAIL: Build pr22649-2c.so
FAIL: Build pr22649-2d.so
test suite failures and tightening checks made with `pr22649-2a.so' and
`pr22649-2b.so' test cases.
Keep the original empty action with `pr22649-2c.so' and `pr22649-2d.so'
links and MIPS/ELF targets though, because for them the linker does not
garbage-collect the `.reginfo' section. This is because the section has
its flags set differently by code in GAS in `md_begin':
if (strncmp (TARGET_OS, "elf", 3) != 0)
flags |= SEC_ALLOC | SEC_LOAD;
and consequently BFD linker code in `_bfd_elf_gc_mark_extra_sections':
else if (((isec->flags & SEC_DEBUGGING) != 0
|| (isec->flags & (SEC_ALLOC | SEC_LOAD | SEC_RELOC)) == 0)
&& elf_next_in_group (isec) == NULL)
isec->gc_mark = 1;
marks these sections to be kept due to their SEC_ALLOC, SEC_LOAD and
SEC_RELOC flags all being zero (`.reginfo' sections never have
relocations attached).
