New comment by r-ricci on void-packages repository

https://github.com/void-linux/void-packages/pull/41188#issuecomment-1570941191

Comment:
@jcgruenhage I made some other changes and cleanups on top of your work.
Now it builds on musl and cross-compiles.
I disabled rar support because its code is source-available but [proprietary](https://github.com/Cisco-Talos/clamav/blob/clamav-1.1.0/libclamunrar/license.txt).
I also enabled optimization for rust code.

This is the diff compared to current master:
