Seems to be broken by http://gcc.gnu.org/ml/gcc-patches/2012-05/msg00163.html
The assumption that only alpha-vms doesn't define ASM_OUTPUT_ADDR_DIFF_ELT
doesn't seem to be true.
echo `for i in config/*/; do grep -q ASM_OUTPUT_ADDR_DIFF_ELT $i/* || echo $i;
done`
config/avr/ config/m32c/ config/mep/ config/moxie/ config/picochip/
config/stormy16/ config/vms/
