A heads up.

This tweaks the way the compiler is run so that it is forced to look in 
.jars for pre-compiled .class files (and not accidently re-compile a 
.java file).  (tks to tromey for figuring out the problem).

With this in place, I'm able to built frysk on f8 with the 
--enable-jar-compile option.  That option enables the "faster" sequence 
.java->.class->.jar->.o vs the slower .java->.o path.  Going forward 
this option is likely to be made the default.
