[Buildroot] [PATCH] package/systemtap: new package

[Ralph Siemsen]

SystemTap provides a simple command line interface and scripting
language for writing instrumentation for a live running kernel plus
user-space applications.

This is a minimal implementation; not all supported features of
systemtap are enabled.

Note that I am not a systemtap expert, in fact, I only got involved
helping someone else get this to build under buildroot. Hence YMMV.
Yann requested that I post this patch to the list, so here we are.
