One of the recent x32 commit broke the build on some configs:

  VDSO    arch/x86/vdso/vdsox32.so.dbg
/usr/bin/ld: arch/x86/vdso/vgetcpu-x32.o: relocation R_X86_64_64 
against symbol `.rodata' isn't supported in x32 mode
arch/x86/vdso/vgetcpu-x32.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status

config attached.

binutils-2.21.51, gcc-4.7.0.

Thanks,

	Ingo
