While playing with jit3 (for arm), I surfed the net to find some info
of QEMU for Xscale (official 0.9.0 does not have it, but patch is
available), and found interesting story for ABI.

According to
gcc for arm now can support two different ABI, and I have no idea
which becomes default for gcc-4.1. This is another thing what I have
to check.

Of course, Steven or Sascha mentioned something for EABI, but when
I first read them, I just think this is only for the floating point.

After the build for jit3, I will invoke another build with explicitly
specify '-mabi=apcs-gnu -mfpu=fpa' and check the result. As several of
you may know, QEMU emulated arm is not first enough for me to do two
build job at one time ;-)

P.S. BTW, I still use 'jikes' on this machine because it slighly
     shortens my build time ;-)
