What's the right way to launch the bourne shell from a makefile? I had
assumed the ${SHELL} variable would be set to "the right" copy
of /bin/sh (like maybe the one in tmp or legacy at various stages). It
appears that that's not the case, and ${SHELL} is whatever comes from
the environment, which can lead to using csh or bash or whatever.
I see some of our makefiles use just a bare "sh" which seems reasonable
to me, but I don't want to glitch this in src/include/Makefile again.
The goal is to run a script in src/include/Makefile by launching sh with
the script name (as opposed to launching the script and letting the #!
do its thing, which doesn't work if the source dir is mounted noexec).
