The version of clang we have in FreeBSD is unable to build FreeBSD/ARM
binaries. I have a patch to support, however, while it produces a
working kernel, all userland programs crash before they get into main().

The problem I'm having with userland appears to be in crtend.o in the
__do_global_ctors_aux function. It loads a list of functions to call
but appears to be attempting to call a NULL pointer. I'm not yet sure
the cause of this.
