[kaffe] Bug Report PowerPC build

[David.Cowan@apcc.com]

I am cross compiling kaffe 1.1.1 to run on an embedded linux platform.  I
have a working build that will run hello world but as soon as I try to do a
Thread.sleep the sleep waits forever.   It is a power pc platform.  I am
using unix-jthread

Here is a copy of my arguments to configure

$ ./configure --host=ppc-linux --build=i686-linux CC=ppc_8xx-gcc
AR=ppc_8xx-ar LD=ppc_8xx-ld NM=ppc_8xx-nm --with-rt-jar=/tmp/rt.jar
--without-x --with-libffi --with-engine=intrp --with-libraries=/tmp/lib
--with-includes=/usr/local/libffi-1.20/include
--prefix=/home/test/kaffe-bin

I have looked down into thread.c to see the native method for sleep and
don't really see were a native sleep is called.   Is there a vmdebug flag I
could use that might help debug this?
