On x86_64, newish gcc will use relocation types R_X86_64_GOTPCREL,
R_X86_64_GOTPCREL64, R_X86_64_GOTPCRELX, and R_X86_64_REX_GOTPCRELX,
which our _relocate() does not support, for extern declarations visible
to things linking against a DSO. Since we're really just building a .a
here, and *nothing* needs to be exported in the .so sense, we don't need
any of that optimization at all, there's no point in making _relocate()
know how to handle these.
Instead, this patch simply removes the visibility from everything in the
.a, which gets us back to fairly normal relative relocations that wind
up being R_X86_64_RELATIVE in the final binary, which we can handle.
