OK.  After giving this a whirl (after a NAK from Matt, privately), it looks
like some versions of binutils don't make proper use of -many (in 2.14 it
will override ppc_cpu, and PPC_OPCODE_ANY doesn't look to be used).  So
that brings us to the following patch.  Olaf, can you please verify this
still works for you?  Paul, is this OK with you?

This is not enough.
as needs -many (or at least -maltivec) unconditionally for binutils 2.15
gcc needs also -maltivec because -mppc seems to disable -maltivec again.

Hmm.  So with binutils 2.14, we need to do -many,-mppc as -many will
zero out all previous flags.  On binutils 2.15, -mppc always resets
the cpu_flags, thus clearing out -many.  -mppc64bridge, -me500 and
-m405/etc all do the same.  So far we end up being lucky, imho, that
don't trip over this on !CONFIG_6xx.  So while I'm not exactly happy
we have to do this, the following is the least ugly fix for this:
