The fix defines __USE_GNU before including <stdio.h> in case it isn't already
defined. After this intervention the module compiles OK.
Instead of interventions, I believe the standard way to do this is to simply
define _GNU_SOURCE before including the header file(s). For example, the
following also fixes the compilation failure on Ubuntu:
diff --git a/tools/testing/selftests/sgx/main.c b/tools/testing/selftests/sgx/main.c
index 9820b3809c69..bb6e795d06e2 100644

However, that's not required, because Edward Liaw is already on v4 of
a patchset[1] that fixes up the _GNU_SOURCE problem for all selftests.
