[Buildroot] [PATCH 1/1] ccache: fix initial setup failure

[Danomi Manchego]

The BR2_CCACHE_INITIAL_SETUP can fail if CCACHE_DISABLE is defined in the
environment, because ccache refuses to create a ccache.conf file when
caching is disabled.  To avoid this failure, we unset CCACHE_DISABLE prior
to doing any initial cache setup, just on the call setting up the initial
config.  The rest of the build can proceed with CCACHE_DISABLE set, if the
user wishes it so.
