CCACHE_DISABLE was added to bitbake.conf in oe-core dd2bab (June 2012) because autogen-native exports HOME=/dev/null during the build, which is then used by a host ccache to construct the path to it's cache (/dev/null/.ccache) and this fails. However we now always export CCACHE_DIR to solve the same problem in a more efficient way so CCACHE_DISABLE can be deleted.
