experimental gcj support added to kaffe

[Amol Kulkarni]

Hi,

I've been having the same problem as Pavel. Only in my case I get warnings
about --sjponthrow, and then gcc bails out saying that the size of the
object --sjponthrow has changed from 226 to 237.

giving the --disable-gcj flag had no effect, so I finally ended up
removing  libgcj.la from the Makekile in kaffe/kaffevm (which I'm not sure
was a good thing to do). However it worked. (but maybe I should try
Godmar's suggestion).

However, now I have another problem, this time with jthreads. I think I'm
missing some library. 

But I might have messed up somewhere, so please bear with me since I'm a
newbie. I'd be grateful for your suggestions/comments about this. I'm
including the output below.

Thanks,
Amol
