Define HAVE_LD_R_386_GOT32X to 1 if 32-bit x86 assembler generates
R_386_GOT32X for "jmp *foo@GOT". Define HAVE_LD_R_X86_64_GOTPCRELX
to 1 if 64-bit x86 assembler generates R_X86_64_GOTPCRELX for
"jmp *foo@GOTPCREL(%rip)".
* configure.ac (HAVE_LD_R_386_GOT32X): New. Defined to 1
if 32-bit assembler generates R_386_GOT32X for "jmp *foo@GOT".
Otherise, defined to 0.
(HAVE_LD_R_X86_64_GOTPCRELX): New. Defined to 1 if 64-bit
x86 assembler generates R_X86_64_GOTPCRELX for
"jmp *foo@GOTPCREL(%rip)".
* config.in: Regenerated.
* configure: Likewise.
