New issue by TrueTechie on void-packages repository

https://github.com/void-linux/void-packages/issues/34190

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  `Void 5.13.19_1 x86_64 GenuineIntel uptodate rFFFFF`

* package:  
  *affected package(s) including the version*: `rtl8822bu-dkms-20201222_1`

### Expected behavior
The module compiles and properly enables Wifi with the adapter.

### Actual behavior
The compilation of the module fails due to not having `bc` installed and gets farther into the process after installing the package before failing once more.

There are other repositories on Github that seem to have a working driver with recent kernels. The following have worked for me:
* https://github.com/RinCat/RTL88x2BU-Linux-Driver (packaged in the AUR)
* https://github.com/morrownr/88x2bu.git

Error in module build process with `bc` installed:

### Steps to reproduce the behavior

2) Install `rtl8822bu-dkms`
