It's just not perfect, that's all. QEMU (and other VM platforms) can't emulate everything, and this is just one of those times.
Since you use VMware to virtual Arch Linux ARM Linux, I'm assuming you're using it to compile things faster, right?
If so, you may want to instead just use Arch Linux (x86) in a VM, install distcc onto both your plug and the Arch x86 VM, and then see http://plugboxlinux.org/wiki/index.php5 ... ith_distcc
to make a cross-compiler. It's many times faster than using QEMU.
