+Subject: [PATCH] Fix crash on startup when using musl
+
+nm_strerror_native_r makes use of a glibc extension to strerror_r
+when _GNU_SOURCE is defined -- even when not using glibc.
+
+musl uses _GNU_SOURCE for some extensions, but doesn't have the
+strerror_r for unknown error codes extension -- resulting in a
+NULL pointer being passed to UTF-8 check functions that don't
+check for it.
+
+Use the non-glibc code path when __GLIBC__ isn't set.
