[yocto] poky ref manual still confuses BB_ENV_WHITELIST and BB_ENV_EXTRAWHITE

[Robert P. J. Day]

  in ref manual, B.5, "Running a Task",

"Tell BitBake to load what you want from the environment into the data
store. You can do so through the BB_ENV_WHITELIST variable. For
example, assume you want to prevent the build system from accessing
your $HOME/.ccache directory. The following command tells BitBake to
load CCACHE_DIR from the environment into the data store:

     export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE CCACHE_DIR""

  as you can see, the para refers to one variable, while the export
command refers to another.  not sure how someone wants to word that so
i'll leave it for someone else to fix.
