[PATCH] conf/bitbake.conf: fix reparsing after -p is used

[PATCH] conf/bitbake.conf: fix reparsing after -p is used

[Paul Eggleton]

The bitbake wrapper script is set up such that the -p (--parse-only)
command line option is not executed under pseudo, and it sets the
PSEUDO_BUILD variable to indicate whether or not pseudo is being used.
Since PSEUDO_BUILD is allowed through into the environment via
BB_ENV_EXTRAWHITE it influences the data hash and thus if you run
"bitbake -p" and then run bitbake again to actually build something, the
change to PSEUDO_BUILD causes the cache from the -p execution not to be
used. This is fixed simply by adding PSEUDO_BUILD to
BB_HASHCONFIG_WHITELIST in bitbake.conf so that it doesn't influence the
data hash.

Fixes [YOCTO #2600].
