This can be a dangerous change and probably does not have the intended
effect ((project) global ccache dir) due to

| do_clean[cleandirs] += "${CCACHE_DIR}"


imo, this class should be removed completely (${PN} local ccache dirs do
not make any sense) and the only useful part

| CCACHE_DISABLE[unexport] = "1"

should be solved by http://patchwork.openembedded.org/patch/32787/
