[packagekit] Werror and maintainer-mode

[Mounir Lamouri]

Hi,

I think Werror should be removed or be optional in packagekit. You can see the
reasons here [1].
We talked about that quickly a few weeks ago and the idea that showed up was to
enable it with maintainer-mode enabled. Actually, maintainer-mode is not
available in packagekit configure script (it should be removed from autogen by
the way) and maintainer-mode shouldn't be used for that [2].

I see two solutions:
- automatically add -Werror when --enable-local is set.
- add a new option --enable-strict which will enable this flag.

Thanks,
Mounir
