I see.  Yes, very unfortunate indeed.

I'm a bit reluctant to change autogen.sh in that way.  autogen.sh has a
defined behavior which is to call configure with "$@".  Tools like jhbuild
rely on that.

That said, 1) our autogen.sh is really just a vanilla wrapper around
autoreconf, so you can call it directly instead, and 2) I've had good luck
using ACLOCAL_FLAGS most of the time.  Not sure if it works in this case.
