I tried this and is does work.  The downside is  a couple of the 64bit tests
fail.  Obviously I can check for -maix64 first..

Looking closer at the problem showed it to be a conflict with the finding the
correct multilib.    The combination of options -maix64 -mcp=powerpc returns
the default libgcc.  I  would have thought it would have been resolved to
ppc64.
