You can support all the extensions without using the `scriptinstall'
by adding implicit rules.

It would be nice to support multiple programs in general for the case
where there is only one source file per program and a simple rule for
transforming the source name to the target name.  Trivial makefiles
already get the build step right:

	$ echo 'all: foo bar' >makefile
	$ touch foo.c bar.sh
	$ make -n
	cc -O2 foo.c  -o foo
	cp -p bar.sh bar
	chmod a+x bar

This could be made to work in the bsd.prog.mk framework without depending
on implicit rules.  E.g., use ${PROGS} for the list of simple programs
and substitute in it to get the C programs, etc, and generate an explicit
rule for each.

... Here is an half finished implementation.  The obj directory stuff
isn't quite right.  I cut this out of bsd.man.mk and deleted one too
many complication from the install rule.
