Subject: bitbake: data_smart: Cache the fact a variable accesses another even if its unset
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d6ac67f9afbd431ed308d6513730217cce0d689d;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

bitbake: data_smart: Cache the fact a variable accesses another even if its unset

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.
