Based on a different request, I checked in a tool that compiles CEDET
from w/in Emacs only in cedet-build.el.  It only handles the Emacs
Lisp part.  There are three kinds of targets it will build, including
autoload files, grammar files, and general Lisp files.  Order is
important since the build process uses the tool it's compiling, so
compilation bootstrapping is fragile.

That build script will likely make it easier for package.el, but it
needs to be run in a fresh emacs like this:

emacs -q -l cedet-build.el -f cedet-build

and after it's built, you really need to exit Emacs so the compiled
versions can be loaded for performance reasons.
