This is broken; please read:

This is likely caused by an upgrade to Autoconf-2.60, not the Automake
upgrade; this part of autoconf/NEWS explains it:

The links provided above point out several possible solutions. Another
recent one is the Gnulib module `configmake':
http://lists.gnu.org/archive/html/bug-gnulib/2006-08/msg00252.html
Whatever suits you best, the one you've used so far is not supported and
will eventually break again when some other variable change is
necessary.
Hope that helps.
Cheers,
Ralf
