We have the handler, which allows for it to be done properly[1].

1. http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/conf/machine/include/imx-base.inc#n68

Including 'qtbase' here will make it to move all packages depending on
it for the subarch.

The real long term solution is to try to split it and make the QPA
package machine specific. I don't know if it is possible.
