From 3901cb515762aee9b6af67216419a9c5b83eec3d Mon Sep 17 00:00:00 2001 From: Gustavo Zacarias Date: Thu, 15 Oct 2015 10:24:39 -0300 Subject: [PATCH] ccache: allow for BR2_CCACHE_DIR environment override Allow the BR2_CCACHE_DIR .config option to be overriden by the BR2_CCACHE_DIR env variable. This is useful for big projects where in some cases the developers home directory might be a NFS mount (slow) and real production builds aren't. Update documentation accordingly as well.
