I think it makes more sense to have them at the end because they are not
really common options that people would use.  They are being added because
the GNU Coding Standards require them (and having them means that distro
build systems that expect a standard configure script can pass typical
options without complaints).

I'll add them to the help.

Should be done in a separate patch.
