Geeze, what was I thinking again?  Replace all references to:

	${DISTDIR}/${DISTNAME}${EXTRACT_SUFX}

With simply `${DISTFILE}' which defaults to the above.  This lets you
easily name distribution files that don't cooperate with any rational
naming syntax.

Similarly, make a variable called ${PKGFILE} which fills the same purpose
for packages.

Just trying to make this thing really really general to suit every need.
Now I need somebody to figure out how to make the extract target auto-fetch
things from ${HOME_LOCATION} with ncftp *if* ncftp is installed and it
looks possible to reach the foreign site.  That will take some fancy footwork,
but would be slick.  I've changed this too so that HOME_LOCATION is no longer
set by default, allowing you to do an .if defined(..) check for it.  The
extract rule now does this too.
