Bug 1242074 - Avoid going back and forth between FasterMake and RecursiveMake; r=gps FasterMake needs some RecursiveMake install manifests to have been processed before doing its work, so we can actually end up processing them twice because of the going back and forth from FasterMake in the hybrid build system. Set the dependency at the RecursiveMake level when doing an hybrid build.
