--- Comment #40 from cbaylis at gcc dot gnu.org ---
The kernel does support a mechanism to add a command line option for only
compilers which support it.

Documentation/kbuild/makefiles.txt:
    cc-option
        cc-option is used to check if $(CC) supports a given option, and if
        not supported to use an optional second option.

I think you could therefore add this line to arch/arm64/Makefile
KBUILD_CFLAGS   += $(call cc-option,-mpc-relative-literal-loads)
