Instead of going to qmake to generate the makefile that we want, we write
the makefile directly and include it from the generated makefile. This
leaves us with a single top level makefile for handling exclusive builds
through xcodebuild, and covers all the various build configurations in
a unified manner. It also allows for improved test device handling.
