Which is something you should never do.
Portage does not know that you did this, and with the next emerge it
will revert back to whatever is in the various config files, which you
will have forgotten, and you will pull your hair out for hours trying
to figure out what the problem is. For the second time.
Don't change env vars on the command line to modify portage's behaviour,
instead use the relevant config file, unless such a file really really
doe snot exist.
