[PATCH] gnumakefile: work without maintainer-makefile

[Eric Blake]

With gnumakefile being an independent module from maintainer-makefile,
we shouldn't have a hard requirement on maint.mk.

* top/GNUmakefile: Let maint.mk be optional.
Reported by Simon Josefsson.

This is an alternative to merging the 'gnumakefile' and
'maintainer-makefile' modules.  I'm posting it more as a
demonstration that it is possible, because I personally like
the idea of the module merge.
