Makefile: make sure cargo build is always ran

The build targets only depend on the init binary target, so running `make`
after changing some other part of the source code doesn't trigger a rebuild.

Make the LIBRARY_RELEASE_* and LIBRARY_DEBUG_* targets .PHONY to make sure the
library is always rebuilt when running `make`.
