[PATCH RESEND] x86: relocs: Make per_cpu_load_addr static

[Ben Hutchings]

per_cpu_load_addr is only used for 64-bit relocations, but is declared
in both configurations of relocs.c - with different types.  This has
undefined behaviour in general.  GNU ld is documented to use the
larger size in this case, but other tools may differ and some warn
about this.
