Hi RP,
Do you have any comments on this, please? It's really very useful during
development. It can save both configure and compile time in the second run,
It can save about 8 minutes (30m -> 22m) if I rebuild core-image-minimal
totally without any sstate caches.

* V3
- Make cache files can be shared between different build dirs
- Add task do_cleanccache
- Make cmake work with ccache
- Upgrade ccache to 3.5, this version has a debug mode, which is useful for
figuring out why a cache file is not used.
* V2
- Fix comments from Martin Jansa and Martin Hundebøll.
- Fix RP's comments:
1) Add comments for ccache related code in base.bbclass
2) Remove all ccache-native's dependencies so that all recipes can depend
on
and use it.
- Update test_ccache_tool in oeqa
