This is another orphan PowerPC patch from our backlog.
On native PowerPC, GCC supports -mcpu=native, to generate code for the
same processor flavor that GCC itself is running on. This patch makes
it also possible to configure GCC to default to that option.
Tested by building GCC with this configure option and
build=i686-pc-linux-gnu, host=target=powerpc-linux-gnu, and verifying
that the output of running the resulting gcc with --version --verbose
looked sane.
OK to commit?
