Arch Linux

Description:
Since updating to the new x64 build of PCSX2, I'm getting a few benign errors and warnings which may either be the result of packaging or my setup, but it's not clear to me which. If there's anything I've missed out from this ticket (details below) then I would be more than happy to add it on request.

Additional info:
* package version(s)
pcsx2 1.7.0.r202.9c0865c0f-1
wxgtk-common 3.0.5.1-1
wxgtk3 3.0.5.1-1

* config and/or log files etc.

Terminal output:
```
18:30:51: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1013,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1002,wx containers,compatible with 2.8).
```

```
I thought this might be a result of my GTK theme but it happens even when set to Adwaita, so I guess not?

* link to upstream bug report, if any


Steps to reproduce:

Set *any* GTK theme (including Adwaita) and set up QT to use GTK using qt5ct.
Install pcsx2 1.7.0.r202.9c0865c0f-1 from the repo and run it.
