You should be able to delete stamps/overlay.stamp (so the overlay
files are recopied) and run make again.
The options Josh mentions are also very useful for speeding up builds.
 Once you have a build of IcedTea,
it's probably worth copying that somewhere on your system (assuming
you don't already have an IcedTea package)
and using the --with-icedtea and --with-icedtea-home options to use
that.  This avoids having to build twice
(once to bootstrap with ecj/gcj, and once to build icedtea with icedtea).
