<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.

#### Does it build and run successfully? 
(Please choose at least one native build and, if supported, at least one cross build. More are better.)
- [ ] I built this PR locally for my native architecture, (ARCH-LIBC)
- [ ] I built this PR locally for these architectures (if supported. mark crossbuilds):
  - [ ] aarch64-musl
  - [ ] armv7l
  - [ ] armv6l-musl
-->
- [x] I built this PR locally for my native architecture, x86_64
- [x] I built this PR locally for these architectures (if supported. mark crossbuilds):
  - [x] x86_64-musl - failed, added patch and needed `libexecinfo` - still getting errors about backtrace and backtrace_symbols not being defined, not sure exactly what to do about it.
  - [x] armv7l - failed, see [here](https://github.com/TrenchBroom/TrenchBroom/issues/3651) afaik ARM is not supported because of this, but I'm not 100% sure. The error in the builder makes me think a lib is missing, but if that issue is correct - even if we get it working, I don't think the program loads correctly because of shader issues.
  - [x] i686 - success
  - [x] i686 (crossbuild) - failed, `CMake Error: AUTOMOC for target common: Test run of "moc" executable "/usr/i686-pc-linux-gnu/usr/lib/qt5/bin/moc" failed.`

See readme, TB will crash on wayland if `QT_QPA_PLATFORM` is set to `wayland`.
