Comment:
I dunno... it just bothers me to silence all warnings, even those that we didn't cause. :sweat_smile: 

Case in hand - building on musl causes this error to pop up -
https://github.com/void-linux/void-packages/runs/5748101481?check_suite_focus=true#step%3A7%3A54=

This error isn't present on glibc, so my guess is upstream has never tested on musl.  
If we disable all warnings, we won't be able to see these messages, and those message may show some errors that could develop to major problems.
