GNU ld is correct according to the ELF ABI Processor Supplement for
i386 Processors.

In typical use, the .o file will contain a 0xfffffffc in the four
bytes affected by R_386_PC32.  R_386_PC32 is defined to add the PC
relative offset from the start of the 4 byte field to the existing
contents of the 4 byte field.
