"make" SHELL variable

Leaving aside the question of whether absolute consistency is
preferable to not breaking Makefiles, I simply point out that even if
"make" imports the environment variable SHELL it need not use it to
decide which shell to use to run commands!  It can just say "I run
things with '/bin/sh', and that's that."

To put it bluntly, it is incorrect for "make" to cause the behavior
of a Makefile that may be used by several people to build some piece
of software to depend on a user-preference item like the setting of
the SHELL environment variable.  If this causes "make"s behavior to
have a small wart, so be it.

And possibly confuse other programs that use SHELL to determine which
shell to use when handling a "shell escape" command - or, more
likely, confuse the user who tries to use a "shell escape" command.
