From 7acd1f9b7b20f31470630aec41c60134c46e26997d88f72dc27574ee2e03b2f5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Accepting request 756128 from
 home:StefanBruens:branches:GNOME:Factory

libgtk3 takes ~15 minutes to build, the API docs about 3 hours.

Putting the API-docs into a separate package removes 23MByte from a gtk3-devel install.

- Split API doc generation from main package using _multibuild,
  libgtk3 itself only takes a fraction of the time to build.
