Note to packagers: the Makefile was modified to take configure's
--sysconfdir into account as other projects do. As a result, setting
--prefix=/usr will no longer put the configuration files under /etc.
You now need to explicitly pass --sysconfdir=/etc. If you don't,
configuration files will go under /usr/etc, which is not what you want.
This is somewhat less intuitive, but also more consistent with what
other projects are doing.
