I already considered this, but when I tried building this packagegroup 
for musl it failed on some netkit recipes even without my change.

ERROR: Nothing PROVIDES 'mdns' (but /home/bunk/yoctomaster/yocto-test/sources/meta-openembedded/meta-networking/recipes-support/ntp/ntp_4.2.8p13.bb DEPENDS on or otherwise requires it)
mdns was skipped: incompatible with host aarch64-test-linux-musl (not in COMPATIBLE_HOST)
ERROR: Required build target 'ntp' has no buildable providers.
Missing or unbuildable dependency chain was: ['ntp', 'mdns']
