Modify get_reloc_section for targets that map .got.plt to .got
...
Fixes tic6x testsuite failures due to .rela.plt having a zero sh_info.
I considered passing link_info to get_reloc_section so we could
directly return the .got.plt output section, but we need the fallback
to name lookup anyway for objcopy.
bfd/
* elf.c (_bfd_elf_get_reloc_section): Allow for .got.plt being
mapped to output .got section.
ld/testsuite/
* ld-arm/tls-gdesc-nlazy.g: Adjust for readelf note.
* ld-tic6x/shlib-1.rd: Expect corrected .rela.plt sh_info.
