Glibc-2.30 gained gettid() wrapper, selftests fail to compile:
lib/assert.c:58:14: error: static declaration of ‘gettid’ follows non-static declaration
58 | static pid_t gettid(void)
| ^~~~~~
In file included from /usr/include/unistd.h:1170,
from include/test_util.h:18,
from lib/assert.c:10:
/usr/include/bits/unistd_ext.h:34:16: note: previous declaration of ‘gettid’ was here
34 | extern __pid_t gettid (void) __THROW;
| ^~~~~~
