[CMake] makefile environment variables

[Daniel Stonier]

Its only a convenience thing, so not hugely important.

Usually in a cross-compile environment you run a script (or append to
your .bashrc file) some extra environment variables necessary for the
cross-compile environment. Then you build. If you were just using
Makefiles you can just add these environment variables directly to the
Makefile. With the CMake layer there though, I can't do that - can set
them in CMake itself, but it'd be nice if it would transfer these to
the Makefile as well.
