Add GYP build for the src/tools directory on Mac and Linux.

This GYP-ifies the src/processor and src/common directories on those platforms
as well. The Makefile build uses much more granular unittest executables, so
the new processor_unittests does not yet link because of multiple main() symbols,
but this will be fixed later.

Update issue 575
