nmake/jom: Only warn about bad VS environment if compiler not found.

nmake and jom generators no longer warn about missing INCLUDE/LIB
environment variables unless the C/CXX compiler cannot be found.  This
is useful if the user does not want to use these generators with the
Visual C++ compiler, or they do not want to enable any language.
