From bc5f293b151b9ba0d6660814d88ee5041efce318 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 15 Aug 2011 14:05:21 +0100 Subject: gcc: Fix multilib baselib confusion Commit 35fa8dc5f7da90fdd40091a3c3600d3fcd232922 changed the gcc recipes to use baselib for the compiler location. This is fine as long as baselib happens to match the platform multilib definition which is enabled at the time. This patch fixes things so that gcc will honour whatever ${base_libdir} is set to re-allowing suitable customisation of the system layout.
