Subject: [PATCH v1 01/10] selftests/sgx: Compile with -D_GNU_SOURCE

809216233555 ("selftests/harness: remove use of LINE_MAX") introduced
asprintf into kselftest_harness.h, which is a GNU extension and needs
_GNU_SOURCE to either be defined prior to including headers or with the
-D_GNU_SOURCE flag passed to the compiler.

Fixes: 809216233555 ("selftests/harness: remove use of LINE_MAX")
Reported-by: kernel test robot <oliver.sang@...el.com>
Closes: https://lore.kernel.org/oe-lkp/202404301040.3bea5782-oliver.sang@intel.com
