Just one thing I am not able to understand. How does changing the minimum-architecture will results into this build failure. GHA is using same gcc for other PRs as well and they are totally working fine. And in this PR I haven't interfered with GCC at all. 

If any error then I was expecting more of running into SIGILL but certainly not a compile failure.
