[OE-core] one more curiosity about oe-buildenv-internal: what's with BBEXTRA?

[Robert P. J. Day]

  apparently, given the following in oe-buildenv-internal:

BITBAKEDIR="$OEROOT/bitbake$BBEXTRA/"

you can use BBEXTRA to use a different bitbake directory than the
default.  is this a debugging aid?  are normal users meant to know
about this?  i don't see any mention of it anywhere.  in fact, from
the top level of oe-core:

$ grep -r BBEXTRA *
scripts/oe-buildenv-internal:BITBAKEDIR="$OEROOT/bitbake$BBEXTRA/"
$

rday
