From db443f263a6d51ce6da6557d825a453676f6c664 Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Fri, 2 Aug 2013 09:33:54 +0200 Subject: [PATCH] host-ccache: turn into a proper dependency This patch moves the host-ccache build target from BASE_TARGETS in Makefile to an actual host prerequisite in support/dependencies. This causes host-ccache to be built as part of the dependencies, before any real package is built. Since the dependencies are built without ccache anyway, there is no need to set HOST_CCACHE_CONF_ENV anymore.
