Support C++ in libtools.make and rewrite dependency handling.
- Change suffix of objects and depencency files to keep the original file
suffix. This makes it easy to distinguish between C and C++ files when
building and avoids implicit make rules trying to build in a way we don't
want to.
- Implicitly handle dependencies instead of having an explicit rule. Simplifies
things a bit.
- Support C++ files by adding an explicit rule for them. With keeping the
original file suffixes this becomes quite simple.
To use C++ files simply add them to SOURCES (or LIBSOURCES).
