new gcc wrapper, entirely specfile based
the _concept_ of this wrapper has been tested extensively, but the integration with the build/install system, and using a persistent specfile rather than one generated at build-time, have not been heavily tested and may need minor tweaks. this approach should be a lot more robust (and easier to improve) than writing a shell script that's responsible for trying to mimic gcc's logic about whether it's compiling or linking, building shared libs or executable files, etc. it's also lighter weight and should result in mildly faster builds when using the wrapper.
