#2020/01/30 Patch has not yet been accepted upstream
From c81b8fe3e63b7267ac8f6aeea86811acd888e8e9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/4] Fix threads on musl libc
Musl libc does not add any content to _CS_GNU_LIBPTHREAD_VERSION, causing the
runtime check to make sure the thread implementation is NPTL to fail. There
seems to be no way to test not NPTL at run time on musl, so if the configuration
value is empty, just assume the thread implementation is good enough.
