Closed issue by laserbat on void-packages repository

https://github.com/void-linux/void-packages/issues/6949

Description:
### System

* xuname:  
  *xuname: Void 4.20.1_1 x86_64 AuthenticAMD uptodate rrrmFFFFFFFF*
* package:  
  *musescore-3.0_1*
  *qt5-tools-5.11.3_3*

I'm not sure if this issue will be taken seriously, but it seems pretty bizarre for me, especially since void is positioned as minimalist linux distro.

As far as I can understand the issue, clang should be optional dependency of qt5-tools, like it is in arch linux, since it's a very big package and is unnecessary for most functionality of qt5-tools. Since xbps has no support for optional dependencies, I suggest splitting  clang-dependant part of qt5-tools into a separate package, like qt5-tools-qdoc

If maintainers agree to this decision, I'd be happy to provide a pull-request to split qt5-tools.
