We can probably disable libgomp for v7 automatically in buildroot, i'll
give it a shot tomorrow time allowing.

Ok, will be nice to have them when they're available.
In the mean time i've restricted the gcc selection in BR to 4.4.x for LEON.

Yes, the uclibc patch is huge so it's probably pending approval for the
