That's not as important, gnu-build-system is often used as base for
packages and build system, that don't actually have configure.  For
disabled tests, however, it is not clear without comment whether they
fail or whether they simply don't exist.

You'd add the packages, that define those programs as inputs, then
you do something along the lines of

  (substitute* "yadm" 
    (("(.*)_PROGRAM=\"(.*)\"" all var prog)
     (format #f "~a_PROGRAM=~s" var (which prog))))

inside some phase after unpack.
Please apologize if the snippet above doesn't actually work for your
case, I haven't tried it.

By the way, git format-patch seems to swallow the Umlaut (or however
it's called in your language) in your surname.  If you want it to be
that way, then fair enough, just know that there's no policy
prohibiting UTF-8 in committer names.

Regards,
Leo
