Udev has this: http://git.kernel.org/?p=linux/hotplug/udev.git;a=patch;h=67a77c8bf299f6264f001677becd056316ebce2f

I backported that kernel patch to 2.6.32 since I can test that, but the systemd tests were all run with 2.6.37. The problem is that eglibc was built against yet another different version of headers, which lacked the syscall for arm.
