[U-Boot] [PATCH v2] [x86] Don't relocate symbols which point to things that aren't relocated

[Gabe Black]

I don't think the symbols that are left in place are compiled or linked any
differently than the rest, and I believe the compiler/linker is explicitly
instructed to leave relocation information in the final binary. You could
leave those out as a space saving optimization, although that seems like
it's outside the scope of this change.
