Richard, I understand we are late in the release cycle however this
change is indeed required to fix our build of Qt5 using Poky
distribution.

The patch seems fairly safe and should have no impact for current
metadata, while it allow for meta-qt5 to fix the Poky support. The
patch has been sent on Feb and ended being forgotten in the merge
queue however it is being used daily by the World Build test from
Martin, which includes it so static libraries can be disabled.

Please consider it for 2.1.

Best Regards,
