[kaffe] debugging kaffe117 on the arm (iphone)

Unfortunately a gdb debugger is currently not possible on the iphone. Moreover I
have to disable debug and vmdebug just to be able to compile/link so both options
aren't possible.

I've decided to move on to 1.1.8 instead (hence my other post), hoping for the best
after noticing the --enable-scale configure flag.
