 IUC, the 'missing' program will only be used if there is no makeinfo installed
on the system. So if your build host happens to have makeinfo, the documentation
will be built after all.

 I don't think that is a good thing, so ac_cv_prog_MAKEINFO=missing should
probably be added as well...

 Maybe an easier workaround is to add a directory support/wrappers in the PATH
that has empty definitions or other wrappers for programs that we want to work
around.
