XLR Linux/MIPS kernel build error

[Ralf Baechle <ralf@linux-mips.org>]

I'm getting a build error with gcc 4.6.0 and binutils 2.21:

[...]
  AS      arch/mips/kernel/entry.o
  AS      arch/mips/kernel/genex.o
/home/ralf/src/linux/upstream-linus/arch/mips/kernel/genex.S: Assembler 
messages:

error!
Assertion failure in append_insn at ../../gas/config/tc-mips.c line 2867.
Please report this bug.
make[4]: *** [arch/mips/kernel/genex.o] Error 1

make[1]: *** [sub-make] Error 2
make: *** [all] Error 2
make: Leaving directory `/home/ralf/src/linux/obj/nlm_xlr-build'

Not sure what's blowin up there and I haven't had a chance to try other
binutils versions yet.  Is this something known?  None of the other MIPS
kernel defconfigs is encountering this issue.
