Roman Yeryomin d0b8cc7732 build: improve ccache support ... Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin <roman@advem.lv>		2021-01-02 12:08:17 +08:00
