[gtkada] cosmetic suggestions in Makefiles

[Nicolas Boulenguez]

Hello.
You may be interested in a few cosmetic suggestions.

"./configure --help" claims that it handles CPPFLAGS, but
src/Makefile.in ignores them.  The patch below should fix that.

The distclean target
- forgets to clean a few generated files
- forgets to clean a generated  directory
- cleans gtkada_install_static*.gpr (which are not generated).
I have written
"if test -e Makefile; then $(MAKE) distclean; fi" instead of "-$(MAKE) clean"
and "rm -f" instead of "-rm -f"
to see unexpected failures.
