 There are a number of places, most commonly dealing with message file
 generation but a few other places as well, where the rules in Makefile.am
 break when doing parallel builds. "Break" in this context means that
 multiple make jobs can try to execute the rules which is really bad. In
 the case of generating rrttype.h it is catastrophic with large numbers of
 parallel builds.

 Fix the make files to make multiple targets all gate behind a single stamp
 file, which ensures that only one job server will ever generate the
 file(s).
