In theory you can set QT_PACKAGES_ARCH to MACHINE_ARCH in rpi-base.inc
to make it explicit, but that's also really bad (as e.g. rpi2 and rpi3
will each build it's own qtwebengine and all it's deps even when it
should be the same for both).

I think the only usable solution is to let DISTRO to decide the policy,
as Khem suggested DISTRO_FEATURES is first step, if it isn't enough (in
this case it's difficult to distinguish e.g. opengl and gles2 when there
is opengl in DISTRO_FEATURES). So I would leave it to DISTRO maintainers
to decide if they can enable "gles2 eglfs" globally for all MACHINEs in
distro bbappend, or they can enable it only for some DEFAULT_TUNE (or
e.g. for all arm MACHINEs and leave desktop gl for x86).

But forcing this policy from BSP is bad.

Regards,
