[kaffe] darwin5 and darwin6 status after latest changes

[Riccardo Mottola]

Hello,

thanks to he work of dalibor and guilhem, the darwin status is quite 
improved. Yesterday night, my tests reported

- on darwin5
	- pthreads doesn't build, as expected. SOme symbols are missing.
	- jthread builds and we have 2 failues, process task and netwirk interface

- on darwin6 intrp-pthread builds and there are no regression failures 
and also the 3 jni tests pass.

cheers,
    Riccardo
