Comment 46 for bug 1921518

> How will you test that the change does not regress any wget behavior?

In default Ubuntu configuration, either no openssl configuration is provided, or it contains no settings that affect wget. This code path changes how/when openssl configuration is loaded and used by openssl. One should verify that:
1) wget continues to work without openssl.cnf
2) wget continues to work with stock ubuntu unmodified openssl.cnf
3) wget continue to honor and use custom TLS settings that one may have specified in openssl.cnf (for example custom engine)

The above three test scenarios cover the changes or regressions that may occur from applying the proposed patch.

(ps. similar for the curl SRU as well)
