Reduce Makefile/gcc prints to clean build output

The gcc commandlines and other prints can be useful, but most of the time they are overwhelming especially for non-C programmers. This silences the prints. To re-enable, set `V=1` like is common with many Makefile/C projects. For example `V=1 make`, `V=1 mix compile`, etc.
