ppc-linux gcc configury patch

Cort recently changed the ppc ld emulation for linux to
make it nicer for AIX to emulate linux. But this also
means we need to tweek gcc's LINK_SPEC. But we can only
do that by either requiring binutils upgrades, or adding
nasty configury.
Here's an attempt at the later. Would someone be so kind
as to try this out with and without current binutils cvs
binaries in your path?
