That causes some build failures, e.g.

In file included from aio_error.c:30:
../sysdeps/unix/sysv/linux/aio_misc.h:38:1: error: ‘__aio_create_helper_thread’
defined but not used [-Werror=unused-function]
   38 | __aio_create_helper_thread (pthread_t *threadp, void *(*tf) (void *),
      | ^~~~~~~~~~~~~~~~~~~~~~~~~~
../sysdeps/unix/sysv/linux/aio_misc.h:29:1: error: ‘__aio_start_notify_thread’ d
efined but not used [-Werror=unused-function]
   29 | __aio_start_notify_thread (void)
      | ^~~~~~~~~~~~~~~~~~~~~~~~~
