lxecg2e.o contains something like
[hjl@gnu-17 tmp]$ cat x.s
.globl bar
.type bar, @function
bar:
movl foo@GOT, %ecx
movl (%ecx), %eax
ret
[hjl@gnu-17 tmp]$ /usr/bin/as --32 -o x.o x.s
[hjl@gnu-17 tmp]$ ld -shared -m elf_i386 x.o
ld: x.o: direct GOT relocation R_386_GOT32 against `foo' without base register
can not be used when making a shared object
ld: final link failed: Bad value
[hjl@gnu-17 tmp]$
The problem is that since linker doesn't know where the GOT base is at
run-time,
it can't properly resolve R_386_GOT32.
