[yocto] tentative list of vars to be dropped from variable glossary

[Rudolf Streif]

Thanks, Richard. Clearer now but not entirely.

> Yes, it removes it from being parsed. I used, for test although not
sensible, BBMASK = "base-passwd". If I then tried building
core-image-minimal it fails with "Nothing provides base-passwd". If one
could use BBMASK to customize images as suggested in
http://www.yoctoproject.org/docs/latest/dev-manual/dev-manual.html#usingpoky-extend-customimage-localconf
then
one would expect the package to be removed indirectly from the image.
However, that does not happen, the build just fails.

That use case makes sense. If I know that I don't include certain packages
like *gpe* in the images I am building then I can speed up the
build/parsing process by masking the recipes and therefore the regular
expression syntax makes perfectly sense.

Thanks,
Rudi
