[kaffe] Sun's javac and compiling rt.jar without debugging symbols

[Rob Gonzalez]

Hi Mark,

Try using KJC (kjc.jar is included in kaffe 1.1.x) or jikes 1.18 instead
of Sun's javac, but include kaffe's rt.jar in the classpath.

Also, I would use 1.1.1 instead of 1.1.0 as there's been a lot of
improvement between the two development releases.

Cheers,
Rob
