With older binutils this is silently accepted as if this was "cmpw",
while often "cmpd" is wanted.  With newer binutils GAS will complain
about this for 64-bit code.  For 32-bit code it still silently assumes
"cmpw" is what is meant.

This one made it into 4.9-rc3 as "powerpc: Convert cmp to cmpd in idle
enter sequence". We need it to build the 4.4 kernel with GCC 6.2, so
my OpenPower firmware builds are failing.

The GCC version does not matter; the binutils version does, however.
