Bug 915122 – www-client/microsoft-edge USE flag needed for qt6

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Robert 2023-10-03 16:26:00 UTC]

It appears that in recent versions of Microsoft edge support for qt6 has been added, resulting in the addition of a `libqt6_shim.so` file to the deb archive the package is extracted from. 

While I haven't dug into the details for all versions it looks like the change happened sometime after version 110.0.1587.69-1. 

I'm no package maintainer but I'd imagine this would need a `qt6` USE flag much like the current `qt5` USE flag to enable/disable it. 

Currently this presents an issue as portage isn't made aware of the dependency to `qtbase` which `libtq6_shim.so` implies.
And this gives rise to preserved-libs issues. 

Below is the output from emerging microsoft-edge (as a rebuild) in its current state which illustrates the issue.
