simplified make-clean handling

no point using distclean, because the context there
is providing clean sources for distribution, but we
use ./mk release which tars everything up before ever
running any build commands.

make-clean is enough

distclean is a stupid gnuism anyway, and most makefiles
that have it will just do the same as clean anyway
