Unfortunately, it won't find things like "Makefile.v7" and "Makefile.usg"
which are the "master" makefiles for some software.  It also won't
find "makefile.old" or a makefile that is packed into a shar or tar
or compress file.

I'd much prefer to fix make so it behaves in a way that seems reasonable.
Importing SHELL from the environment does not seem reasonable.
(Neither does importing TERMCAP, but at least that doesn't actively
break anything).
