aarch64: handle STO_AARCH64_VARIANT_PCS in bfd
Propagate STO_AARCH64_VARIANT_PCS st_other attribute to the output and add DT_AARCH64_VARIANT_PCS dynamic tag if necessary. Mismatching attributes are not diagnosed. bfd/ChangeLog: * elfnn-aarch64.c (elfNN_aarch64_merge_symbol_attribute): New function. (struct elf_aarch64_link_hash_table): Add variant_pcs member. (elfNN_aarch64_allocate_dynrelocs): Update variant_pcs. (elfNN_aarch64_size_dynamic_sections): Add DT_AARCH64_VARIANT_PCS. (elf_backend_merge_symbol_attribute): Define. ld/ChangeLog: * testsuite/ld-aarch64/aarch64-elf.exp: Add new tests. * testsuite/ld-aarch64/variant_pcs-1.s: New asm for tests. * testsuite/ld-aarch64/variant_pcs-2.s: New asm for tests. * testsuite/ld-aarch64/variant_pcs-now.d: New test. * testsuite/ld-aarch64/variant_pcs-r.d: New test. * testsuite/ld-aarch64/variant_pcs-shared.d: New test. * testsuite/ld-aarch64/variant_pcs.ld: New linker script for tests.
