Mask off the least significant bit in GOT offset
The least significant bit in GOT offset is to record whether we have
initialized the GOT entry in R_386_GOT32 processing. We need to mask
it off for R_386_GOT32X.
PR ld/19601
* elf32-i386.c (elf_i386_relocate_section): Mask off the least
significant bit in GOT offset for R_386_GOT32X.
