Don't ICE running selftests if errors were raised [PR99723]

Hi all

this is to address PR 99723.

In the PR GCC crashes as the initialization of common trees is not
performed as no compilation is happening, this is because we raise an
error earlier while processing the arch flags.

This patch changes the code to execute selftests only if no errors
where raised before.

Bootstrapped on aarch64, okay for trunk?

Best Regards

  Andrea
