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
  http://wiki.debian.org/ArmEabiPort
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 ;-)
