Comment (by nickm):

 Okay.  I spent a lot of time tracking this down, and I believe that the
 simplest fix is for us to build our instrumented version of Libevent here
 without openssl support, since we don't actually use Libevent's openssl
 support.

 This bug started happening because Libevent began to require openssl,
 unless you explicitly disable it.

 This bug became confusing because (I think) Libevent introduced this
 requirement while we were suffering from this issue:
 https://github.com/google/oss-fuzz/issues/2836 , and so we went from
 "failing for one reason where the answer was 'just wait a little'" to
 "failing for another reason that needs a fix."

 I've made an OSS-Fuzz PR at https://github.com/google/oss-fuzz/issues/2836
