I also see it on an m1 mini I got when building against openssl 3.

There is -no_warning_for_no_symbols in apple's ranlib. But perhaps
there's another way around this:
We have ssl_protocol_version_to_openssl() in both be-secure-openssl.c
and fe-secure-openssl.c.  Perhaps we should just move it to
protocol_openssl.c?
