X-Git-Tag: rev_ivi_2015_02_04~11003
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b7f9b3b5b49b32010753f86105e005ea3c93dcf3;p=scm%2Fbb%2Ftizen-distro.git

bitbake: data: Optimise flag lookup in build_dependencies

When looking up flag variable dependencies, large chunks of the function
aren't needed. Optimise the function flow accordingly for speed.

(Bitbake rev: 1bf3aee698ad35f6815ea2c75471a96511a29d55)
