[oe] [meta-qt5][PATCH] qtbase: add a config option to optimize for size

[Kwangsub Kim]

Hi Khem,

That’s a good point. Thanks for your review.
I will put the updated patch that checks SELECTED_OPTIMIZATION and determines the default option. Please have a look if it’s acceptable.

BR,
Kwangsub

    We also have global compiler options which will be passed in. So perhaps 
    it should check for -Os in SELECTED_OPTIMIZATION and enable this 
    packageconfig by default if found.
