Subject: [PATCH 0/5] selftests/sgx: Fix compilation errors.

Hi,

This patch series ensures that all SGX selftests succeed when compiling
with optimizations (as tested with -O{0,1,2,3,s} for both gcc 11.3.0 and
clang 14.0.0). The aim of the patches is to avoid reliance on undefined,
compiler-specific behavior that can make the test results fragile.

If deemed useful, I can also include an elementary wrapper shell script to
compile and run the tests for different compilers (gcc/clang) and
optimization levels.

Best,
Jo
