This was fixed in current systemtap git sources by:
commit 0c3087cc827a9e79abcf573e1a7ebfbc0be60c0e
Author: William Cohen <wcohen@redhat.com>
Date: Tue Jul 19 17:38:52 2011 -0400
Add tapset/arm/aux_syscalls.stp
The ARM processor needs to have _arch_ptrace_argstr() function defined
so the kernel-debuginfo smoke test used for the "make installcheck" works.
Cheers,
Mark
