I was wondering if we there could be a way to have gccgo based docker build only
for ppc64 and s390x archs, based on relative stability of gccgo over golang for
these platforms?

This might provide a feasible way to get docker into secondary arcs (ppc64,
s390x) without affecting primary arch.

Is this an acceptable approach? thoughts?
