[Buildroot] Drop support for Qt 5.6? [was: [RFC 1/2] qt5: bump latest version to 5.10.0]

Nimai, All,

On 2018-02-25 17:42 +0000, Nimai Mahajan spake thusly:

> That being said, we use Qt at work on a daily basis and 5.6 is missing tons of new features and security updates, which forced us to

If you upgraded to 5.9, it means the licensing "issue" is not an issue
for you. So, why do you not upgrade to 5.10 for your own project, then?

My position would be to just change the "latest" to be the actual
latest, i.e. 5.10.
