http://www.redhat.com/archives/fedora-maintainers/2007-January/msg00339.html mono-debugger is built without $RPM_OPT_FLAGS due to buggy upstream configure.in. Fix attached, should be acceptable upstream as is. Additionally, adding --disable-dependency-tracking to %configure could make problems like this easier to catch due to cleaner build output, and could result in some build speedups.
