[Po Lu]

branch: master
commit cc6fed326aa491f89cad5cf59f4a8fb7b2863011
Author: Po Lu <luangruo@yahoo.com>

    Repair mailutils configury
    
    * configure.ac (with_mailutils): When processing defaults,
    set to yes-unless-android if with_features.
    (HAVE_MAILUTILS): Later, disable Mailutils if yes-on-android
    and with_android is set.  This is the minimal Emacs build
    for the build machine.  (bug#65190)
