[Gold] problem building linux kernel

I use gold as the default linker here and it's working fine except when
I build the linux kernel:

LD      drivers/built-in.o
  LD      vmlinux.o
  MODPOST vmlinux.o
WARNING: modpost: Found 6 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'

objcopy:arch/x86/boot/compressed/vmlinux.bin: File truncated
make[2]: *** [arch/x86/boot/compressed/vmlinux.bin] Error 1
make[2]: *** Waiting for unfinished jobs....

So I'm forced to use "make LD=/usr/bin/ld.bfd" to get around this error.

Would it be hard to fix this issue in gold or is this a kernel side
problem?
