I think that Xcode clang compiler doesn't allow global register variables.
You can use gcc instead of clang by command line option 'configure.compiler=gcc'
sudo port -v install qemu +target_arm configure.compiler=gcc

@jeweljar, thanks your suggestions seems to work. I have not verified everything works correctly, but I at least can build QEMU.

Works for me with qemu @1.3.0_0 and Xcode 4.5.2 on Mac OS X 10.8 Mountain Lion.
