Properly handle relocs against absolute symbols

Relocations against absolute symbols in shared object should be resolved
at link-time if symbols are bounded locally.  For PC-relative relocation
against absolute symbols, they should be converted to non-PC-relative
relocation in target backend.  If conversion can't be performed, target
backend should detect it and issue an error.  This patch only fixes x86
backends.
