[OE-core] [PATCH 0/1] Integrate ccache-native

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

1) Add ccache as a native tool, for getting it built automatically make
it as the dependency of bzip2; Also, the ccache will be included by SDK
images;

2) Set CCACHE on a per recipe basis and add task 'mkccachedir' to create
the CCACHE_DIR while start a package building;

3) Remove the duplicate 'ccache.inc' from 'meta/class/'.
