It's been tested on actual x86 and x86-64 hardware, as well as qemux86-64 and qemuppc (utrace doesn't currently have support for arm or mips). A couple examples with output have been added to the systemtap entry in the tracing and profiling section of the Yocto wiki: https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#systemtap Please pull into the meta branch of linux-yocto.
