Previously we silently produced broken output for R_386_GOT32X/R_386_GOT32
relocations if they were used to compute the address of the symbol’s global
offset table entry without base register when position-independent code is disabled.
Situation happened because of recent ABI changes. Released ABI mentions that
R_386_GOT32X can be calculated in a two different ways (so we did not follow ABI here
before this patch), but draft ABI also mentions R_386_GOT32 relocation here.
We should use the same calculations for both relocations.
Problem is that we always calculated them as G + A - GOT (offset from end of GOT),
but for case when PIC is disabled, according to i386 ABI calculation should be G + A,
what should produce just an address in GOT finally.
