[OE-core] [CONSOLIDATED PULL 012/113] base.bbclass: Allow buildstats to be optionally supplied

[Saul Wold]

From: Mark Hatle <mark.hatle at windriver.com>

Buildstats should be allowed to be optionally enabled.  It's
recommended that it be enabled via the USER_CLASSES setting.

Alternatively it could be enabled via the INHERIT_DISTRO or
similar mechanism.
