From 2fd257f6c610624f05c8dd3fe1486364af04696f Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 15 Aug 2011 23:59:32 +0100 Subject: multilib: Only build one kernel For a given system we only want one kernel to be built. This change makes the main kernel recipe provide all of the provides of the various enabled multilibs hence allowing it to fulfil all the appropriate dependencies. To make this work a global multilib class file needed to be created. This patch also enables this multi provider functionality for "allarch" packages.
