Linux/PPC support

I have compiled Kaffe on Linux/PPC using libffi for sysdepCallMethod.

The only thing that needed to be modified was SP_OFFSET. For Linux/PPC it
is equal to 0.

I wrote a test that printed the stack using different values of SP_OFFSET
and the real value taken from %r1 (stack pointer register on PowerPC). The
test confirmed that SP_OFFSET is 0.

Some thread-related tests fail, but most other tests pass. Most 
importantly, javac (Kopi) works and produces working bytecode.

Unfortunately, I cannot spend much time playing with Kaffe at work, but I
hope that other people will fix the remaining issues.
