[PATCH 3/6] Enable recipe caching

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

Import BB_HASHBASE_WHITELIST and BB_HASHCONFIG_WHITELIST from OE,
removing some items that are surely OE-specific, and set CACHE. That's
all what's needed to enable bitbake's recipe parsing cache.
