In case of small target images it is too expensive to include full stap package into the image. Because default systemtap package include SystemTap translater and have very deep dependencies on variety of libraries. And in cross compiling environment compilation of SystemTap kernel modules can happen on host for a given target using --sysroot and other proper options.
In order to deploy resulting SystemTap .ko module, one need small set of SystemTap runtime tools like staprun and stapio. systemtap-utils introduces special "small" variant of systemtap build where only SystemTap run-time utilties are built. As result addition on target is quite small.
