Subject: [PATCH] Merge #14564: Adjust configure so that only bip70 is disabled
 when protobuf is missing instead of the GUI

58c5cc9ce7 Adjust configure so that only bip70 is disabled when protobuf is missing instead of the GUI (James Hilliard)

Pull request description:

  This change ensures that the GUI is still built even if protobuf is missing unless --enable-bip70 is passed to configure. If protobuf is present bip70 support will be compiled in unless --disable-bip70 is passed.
