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?
