x86-64: always use unsigned 32-bit reloc for 32-bit addressing w/o base reg
Except for %eip-relative addressing, where we don't have a suitable
relocation type silently wrapping at the 4G boundary, consistently
force use of R_X86_64_32 (in ELF terms) instead of its sign-extending
counterpart. This wasn't right in case there was no base register in
the addressing expression.
