Is it recent enough to build jdk14?
Otherwise I would prefer to go the i386 cross build way.
It's problematic in respect to ports, but from what I've heard
installaing the DEC binary is also manual work.

Well - I can't argue on that, but having at least a runable java is
required today in many cases - even in simple one such as web browsing.

Not an option - I want it for Alpha and I want it native.
