The patch below fixes the build for moxie-elf in a similar fashion to
the recently posted fix for mcore-elf:

http://gcc.gnu.org/ml/gcc-patches/2010-10/msg00650.html

for the same symptoms.  I think the definition of
INCOMING_RETURN_ADDR_RTX is correct; I reverse-engineered it from
sim/moxie.  It's entirely possible that I made a mistake.

Tested with cross to moxie-elf.  OK to commit?
