Bug 1142352 - Add a configure test for the gcc version of the host compiler when cross compiling. r=glandium The duplication of the code higher up is a little bit annoying, but I don't see an easy way to avoid that. It's also still quite far from duplicating everything. I tested locally with a Fennec build that if I bump the requirement from 4.6 to 4.9, I get the expected build error.
