[BFD, LD, AArch64, 1/3] Add support for GNU PROPERTIES in AArch64 for BTI and PAC This is part of the patch series to add support for BTI and PAC in AArch64 linker. This patch implements the following: 1) This extends in the gnu property support in the linker for AArch64 by defining backend hooks for elf_backend_setup_gnu_properties, elf_backend_merge_gnu_properties and elf_backend_parse_gnu_properties. 2) It defines AArch64 specific GNU property GNU_PROPERTY_AARCH64_FEATURE_1_AND and 2 bit for BTI and PAC in it. 3) It also adds support in readelf.c to read and print these new GNU properties in AArch64. All these are made according to the new AArch64 ELF ABI https://developer.arm.com/docs/ihi0056/latest/elf-for-the-arm-64-bit-architecture-aarch64-abi-2018q4 *** bfd/ChangeLog *** 2019-03-13 Sudakshina Das <sudi.das@arm.com> * elf-properties.c (_bfd_elf_link_setup_gnu_properties): Exclude linker created inputs from merge. * elfnn-aarch64.c (struct elf_aarch64_obj_tdata): Add field for GNU_PROPERTY_AARCH64_FEATURE_1_AND properties.
