gcc is one of the few things we don't reautoconf so it doesn't pick up
our libtool. We therefore end up patching libtool in it and binutils
manually which can be a bit of a pain...

I'd love to have a better fix for this. I suspect its taking the path
from some "gcc -print-xxxx" call which returns /usr/lib/../lib on x86_64
so we could try and normalise it at source...

Cheers,

Richard
