Fixes #10366 The one place that actually used was in the legacy printing of ecparams. This has been replaced by the pointtobuf variant. The ecparam app was using one of these functions - this line has just been removed as another PR will remove all the code generated lines.. Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/13294)
