These patches add macros for detecting the linker name and version,
and apply fixes and workarounds needed to link the arm64 kernel with
GNU gold.
Changes since v1:
- moved LD_DEAD_CODE_DATA_ELIMINATION fixes to the beginning of the
patch set and removed mentions of gold
- renamed ld-if-name-version to __ld-ifversion for consistency
- cleaned up the erratum changes in arch/arm64/Makefile
