Thank you for the report, but I don't think this is a bug: the return value 2 means `GNUTLS_FIPS140_LAX`as defined as:
> The library still uses the FIPS140-2 relevant algorithms but all forbidden by FIPS140-2 operations are allowed; this is useful when the application is aware of the followed security policy, and needs to utilize disallowed operations for other reasons (e.g., compatibility).

Therefore, it not only affects self-tests but also is meant to simulate the FIPS behavior. If that is not clear, we can update the comment.
