If you can do this on a Sun, use the normal make coming with it. This make
can keep track of the commands executed to build the targets. So if you
change one of the Flags on one of the commands, make knows, what files to
recompile. If you choose your make macros carefully, you only compile and
link, what is needed to recompile.

Hope this helps.
