[PATCH] selftests/sgx: Fix an enclave built with extended instructions

Creating an enclave with xfrm == 3 disables extended CPU states and instruction sets, like AVX2 and AVX512 inside the enclave. Thus the enclave code has to be built with a compiler which does not produce instructions from the extended instruction sets. Nevertheless certain Linux distributions confg
