Deleting the executable after running it once is certainly valid, but
not something you'd usually want to do.

If you use a Makefile rather than a hypothetical "universal build
system", typing "make clean" will delete any files that can be
regenerated, and "make build" will recreate the file "build" only if it
doesn't exist or has been invalidated (for example if "build.c" has been
modified more recently than "build").  (Determining what depends on what
can be tricky.)

A universal build system should at least provide most of the
functionality provided by existing ones.  If it can only build from
scratch, it's less useful.
