This sounds fine, but it looks like the proposed changes do more than

This part reordered certificates in server-revoked_and_ica.pem. I guess
that is because of wolfSSL using the exact order in which they are
included(?). It is a bit inconvenient when different TLS libraries have
different behavior in this area, but in any case, if this is needed, I
would prefer this to be done in a manner that does not change the PEM
file for other TLS libraries. In other words, instead of modifying this
file, a new file in the other order of certificates should be created
and wolfSSL-based builds could use that.

This looks otherwise reasonable, but why is that client_cert replacement
done based on hapd_tls?

This should likely be done based on hostapd being build with wolfSSL.
