I noticed this test started failing after upgrading to Alpine 3.20 because it expects “ppoll should not be accessible without _GNU_SOURCE
”
However, it is now exposed in musl’s default profile due to being schedlued for inclusion in a future POSIX version; see: https://git.musl-libc.org/cgit/musl/commit/?id=f247462b0831cbf163e976ee9a909748c674b88b
