At the reproducible builds summit we talked about “checkpoints” that we
want to achieve, i.e. points in the build graph that one can arrive at
one way or another (in this case via clang or via GCC) but with the same
hash, so that one could confidently cut the graph at that point and
graft it onto a different root.

GCC 4.7 is one of those points; it is a desirable location in the
bootstrap graph as it doesn’t depend on a C++ compiler.

I agree.

Thanks for this great effort Gábor!
