ccache: allow dynamic selection of cache directory
The existing ccache infrastructure sets the cache directory hardcoded in the ccache binary. As this directory was set to ~/.buildroot-ccache, the cache is not necessarily local (e.g. in corporate environments the home directories may be mounted over NFS.) Previous versions of buildroot did allow to set the cache directory, but this was also hardcoded (so you had to rebuild ccache to change it), plus that support was removed. See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for a discussion on this. This patch modifies ccache to respect a new shell variable (exported from the Makefile, based on a configuration option) instead of CCACHE_DIR. The name CCACHE_DIR itself is already used by autotargets for the ccache package.
