[bitbake-devel] [PATCH 5/8] bitbake: cache: improve debug message

[Robert Yang]

* Print message when cachefile is found/not can help debug.
* Update "Using cache in" to "Cache dir:" since it was the same as the debug
  message of "codeparser & file checksum caches", which caused confusion. And
  whether the cache file will be used or not is still unknown at that time, so
  just print the cache dir.
