[aarch64] Refactor common errata work-around specs
With the addition of the AArch64 NetBSD support code we now have four ports all using and defining the same errata work-around headers. That's silly and long-term becomes a maintenance burden. This patch factors all that code into a single header to eliminate all the duplication. * config/aarch64/aarch64-errata.h: New file. * config/aarch64/aarch64-elf-raw.h (CA53_ERR_835769_SPEC): Delete. (CA53_ERR_843419_SPEC): Delete. (LINK_SPEC): Use AARCH64_ERRATA_LINK_SPEC instead of above. * config/aarch64/aarch64-linux.h: Likewise. * config/aarch64/aarch64-netbsd.h: Likewise. * config/aarch64/aarch64-freebsd.h: Likewise.
