I'm trying to write a make rule that uses the suffix of the source in
the actions.  To give an example, one could write a rule set to install
man pages like so:

.1.man:
	cp $< /usr/local/man/man1/$<

.2.man:
	cp $< /usr/local/man/man2/$<

.3.man:
	cp $< /usr/local/man/man3/$<

and so on for all the variants.  What I'd prefer to do is a single
rule which uses the suffix of the source.

.1.man .2.man .3.man:
	cp $< /usr/local/man/man$(S)/$<

where $(S) is the suffix 1, 2, 3, etc.  Damned if I can find a
way to get the suffix as any of gnu makes canned variables.

Yes, I realize this contrived example would do the wrong thing if
I have both a foo.1 and a foo.3.
