Your expectations that putting a variable into the environment will
override Make variable that is assigned in the Makefile.  (If a
variable is not assigned in the Makefile, but used by one of its
rules, Make will use the value in the environment.)

And anyway, 'CFLAGS="-g3" make' doesn't export CFLAGS into the
environment of programs run by the shell, so this method is simply
wrong, for reasons that have nothing to do with Emacs.
