This patch adds support to enable a linker workaround to a hardware erratum on some early Cortex-A53 revisions. Since the linker option was added very recently, we use xcompile to test whether the toolchain supports it first. It is also guarded by a Kconfig since only a few ARM64 SoCs will need this and it incurs a performance penalty. BRANCH=none BUG=none TEST=Turned it on or off for Smaug and confirmed that it (dis)appeared in verbose make output accordingly.
