Oh, I see why - I was looking on the wrong list. Libvirt patches should
generally be sent to libvir-list.

The automake manual recommends against maintainer mode:

Furthermore, downstream distributions should not require autotools to
build a package if they do not make any changes to any of the
configure.ac/Makefile.am source files in the first place; and
conversely, if you ARE patching those files, then you WANT to rerun the
autotools and not silently disable them.

I'm very reluctant to make this change without a better demonstration
why you think it is needed, and only after exhausting other attempts to
fix the root cause problem that you are really hitting.
