[kaffe] sparc problem identified

[Riccardo]

Hello,

I probably identified the sparc problem: the compare and exchange.

Using the jthread version it works, using the standard one I get on 
Solaris/sparc
/bin/sh ./rebuildLib @essential.files
Compiling classes from  @essential.files  using  /home/multix/kaffe-cvs/
netbsd-68k/kaffe/kaffe/kaffe-bin -verbosegc -mx 256M at.dms.kjc.Main
Segmentation fault - core dumped
gmake[1]: *** [lib/stamp] Error 139


exactly as on the other platforms (linux, openbsd).
