Add `INHERIT += "ccache"` to local.conf or package recipe
to globally activate the ccache functionality.
Add `CCACHE_DISABLE = '1'` to the recipe to disable ccache for it.

+## Using ccache for custom packages
+
+While base system is created from binary debian repositories, some user
+packages are built from sources. It's possible to reduce build time
+for such packages by enabling ccache.
+
+To enable global ccache functionality, `INHERIT += ccache` can be added
+to `local.conf`. If some package requires ccache to be always disabled,
+`USE_CCACHE = "0"` can be used in the recipe.
+
+By default, ccache directory is created inside `TMPDIR`, but it can be
+adjusted by `CCACHE_TOP_DIR` variable in `local.conf`. Ccache directory
+`CCACHE_DIR` default value is `"${CCACHE_TOP_DIR}/${DISTRO}-${DISTRO_ARCH}"`,
+that means caches for different distros and architectures are not overlapped.

What's the status here? I think we still wanted to simplify/unify the
UI, aligning it to ISAR_CROSS_COMPILE.

The new patchset is prepared, but a bit stucked at internal review.
In short, changes in it are the following:
- USE_CCACHE="1" in `local.conf` is used in to enable the feature in general.
- USE_CCACHE="0" can be set in the recipe to avoid caching even if it's
enabled in general
- ccache.bbclass was removed the main ccache-related variables were placed to
bitbake.conf.
