According to the BitBake User Manual the environment variable BB_ENV_EXTRAWHITE
specifies an additional set of variables to allow through (whitelist) from the
external environment into BitBake's datastore. However, running:
$ source oe-init-build-env build-name
will overwrite any pre-existing BB_ENV_EXTRAWHITE variables.
This patch modifies this behaviour: all oe-build-internal BB_ENV_EXTRAWHITE
variables are appended to any potentially already existing BB_ENV_EXTRAWHITE
variables. (The variables are only appended if not already in BB_ENV_EXTRAWHITE)
