[Development] Qt5 build issue for Harmattan

That will not help for several reasons:

1) Harmattan is unmaintained, or at least only just a bit, if any.
2) There are a lot of unresolved bugreports with high priorities. Qt5 would
not be a priority for the platform developers, if there were such people
around.
3) The community cannot update system packages.
4) Applications have to work with older firmwares in app stores, like Ovi,
where older version is available.

Sure, we could, but this will be just a barrier for us to get Qt5 running
on yet another currently available platform. Harmattan is still a shiny Qt
phone for many. Personally, this also demoralizes my packaging effort, if I
need to do such workarounds.

They are actively maintained platforms, which makes a significant
difference in my opinion.

We cannot really fix this within Qt as each implementation is free to define

I would personally appreciate a solution upstream, if possible. I know,
Harmattan is not a tier 1 platform, and will probably never be, but it is a
regression for the build either way. We have had working builds before.
