I had a new look at this. We need a new iteration of this patch, since
the build issue doesn't exist anymore.

However, I would suggest to take a simpler approach:

 - Keep the BR2_PACKAGE_MODEM_MANAGER_LIBMBIM and
   BR2_PACKAGE_MODEM_MANAGER_LIBQMI options.

 - Change modem-manager.mk to test BR2_PACKAGE_LIBMBIM and
   BR2_PACKAGE_QMI instead of BR2_PACKAGE_MODEM_MANAGER_LIBMBIM and
   BR2_PACKAGE_MODEM_MANAGER_LIBQMI.

Also, as was pointed out during the discussion, it would be good to
change the network-manager package to not force the modem-manager
MBIM/QMI support when modem-manager support is enabled. I.e, remove the
following lines:

        select BR2_PACKAGE_MODEM_MANAGER_LIBMBIM
        select BR2_PACKAGE_MODEM_MANAGER_LIBQMI

from package/network-manager/Config.in

Could one of you have a look ?

Thanks a lot!

Thomas
