mach build binaries recurses through js/src and gyp-managed directories every time, because they need to recurse themselves. bug 778236 could address the gyp-managed part, but that would require a tighter integration of gyp than what is in the patch attached there. In the long term, js/src should just be using the top-level build system, which would solve the problem there too, but that's a long road.
