You should have written this version at first. :)

This seems work for me.  I think I tried a similar one but clearly I figured
out the trick of removing nodes.c from ${.ALLSRC}.

Next is usr.bin/ktruss.

$GENCMD provides a way to extract only one output file.  It looks like
complex because it's embedded in makefile.  I don't think it's really complex.
It's just redundant. :)
