If the ust headers are not going to try to replicate all the code from
the systemtap sdt.h file, then they'll need to make a reference to it.
If so, one choice is to make the process manual (have a ust user do
the include before #include <ust/whatever>).  Another choice is for
the ust distribution to autoconf <ust/whatever> based on the existence
of sys/sdt.h header and perhaps #ifdef STAP_PROBEV.
