Expand GOT slots based on whether we are emitting C64 relocations.
This patch only has infrastructure changes, i.e. it only makes
got_header_size a function and adjusts across architectures.
bfd/ChangeLog:
2020-10-20 Siddhesh Poyarekar <siddesh.poyarekar@arm.com>
Tamar Christina <tamar.christina@arm.com>
* elf-bfd.h (elf_backend_data): Make got_header_size a
function. Add callbacks to all targets that use it.
* elflink.c (_bfd_elf_create_got_section,
bfd_elf_gc_common_finalize_got_offsets,
_bfd_elf_common_section): Adjust got_header_size usage.
