Add a MIRROR_DISTFILE variable; defaults to "yes", and should be set

to "no" in a package's Makefile when the authors have placed
restrictions on the redistribution of the distfiles.  (Thanks to Jason
Thorpe for the idea).

Add a `mirror' target, which will do a "make fetch" if the package's
distfile is allowed to be redistributed.  This is for use on sites
which mirror package distfiles.  (Thanks to Charles Hannum for the
idea).
