ld: Add glibc dependency for DT_RELR
When DT_RELR is enabled, to avoid random run-time crash with older glibc
binaries without DT_RELR support, add a GLIBC_ABI_DT_RELR symbol version,
which is provided by glibc with DT_RELR support, dependency on the shared
C library if it provides a GLIBC_2.XX symbol version.
bfd/
* elflink.c (elf_link_add_dt_relr_dependency): New function.
(bfd_elf_size_dynamic_sections): Call
elf_link_add_dt_relr_dependency if DT_RELR is enabled.
ld/
* ld.texi: Mention GLIBC_ABI_DT_RELR in -z pack-relative-relocs
entry.
* testsuite/ld-elf/dt-relr-glibc-1.c: New file.
* testsuite/ld-elf/dt-relr-glibc-1a.rd: Likewise.
* testsuite/ld-elf/dt-relr-glibc-1b.rd: Likewise.
* testsuite/ld-elf/dt-relr.exp: Likewise.
