[bitbake-devel] [PATCH 11/16] data_smart: Cache the fact a variable accesses another even if its unset

[Richard Purdie]

If a variable references another but it isn't set at present, the
reference wasn't stored. It really should be marked as a reference
and the higher level dependency code can handle as appropriate.
