[oe-core] [PATCH 1/1] ccache.bbclass: Allow user to override CCACHE_DIR.

[Paul Sokolovsky]

For example, some users may want to use single cache directory (instead
of per-package) with known max size limit, to better control disk usage.

You change conflicts with

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


To use ccache, it is the best to avoid this class completely and to
remove

| export CCACHE_DISABLE ??= "${@[0,1][d.getVar('CCACHE', True) == '']}"

from bitbake.conf.
