Added the super-cool set of makefiles from Peter Williams which run on
GNU/Linux without NAnt. I named them `makefile.gnu' and not `GNUmakefile'
since this won't break the windows build.
To compile stuff on GNU/Linux, just do a `make -f makefile.gnu'.
* mcs-tool, */makefile.gnu, class/library.make: New files.
