Re: [libvirt] [PATCH] daemon: exclude requirement for probes.h on systems without systemtap

This 1-liner was actually written by Eric Blake, over IRC. It
addresses a compilation failure in make dist and make rpm for
systems without the dtrace/systemtap development libraries
installed.

Given your testing of my one-liner IRC comment:
ACK.
For more explanation for those not following IRC - probes.h is a
generated file, but it can only be generated if you are using dtrace
(systemtap-sdt-devel on Fedora). On the other hand, lack of probes.h
does not affect compilation for people not using dtrace. Unlike
documentation, where we want it to be available even if the user can't
regenerate it, we know that probes.h is safe to omit from the
distribution tarball since the only people using dtrace already have the
tools to regenerate it.
