build: Bail out early if m4 or lex don't exist.

This gives a decent error message on the attempt to run make(1) on a
system where one or both of these essential programs are not installed.

A previous version of the patch used .SHELLSTATUS instead of the
dummy variable, but this did not work with make-4.1 which ships
with Ubuntu-18.04.
