This PR isn't really meant to merge. I put a bit of time into it so if anyone else wants to play with it I figured I would share.
This allows building LE with musl libc support. This replaces glibc. I have made it optional as you can specify with LIBC_VERSION.
There isn't much reason to do this. Overall the resulting tarball was about ~8MB smaller. Musl uses a lot of static linking so there isn't much size reduction because of that. I can't really comment about performance though as I only checked if LE would boot and kodi would run. I only built for RPi4. I'm not sure if the generic build would need more adjustment.s
The amount of patches required for systemd alone makes this a maintenance nightmare and thus why it shouldn't be merged.
Thanks for reading.
