This function is supported down to OpenSSL 0.9.8, which is the oldest version supported since 593d4e4 (from Postgres 10 onwards), and is used since e3bdb2d (from 11 onwards). It is defined as a macro from OpenSSL 0.9.8 to 1.0.2, and as a function in 1.1.0 and newer versions. However, the configure check present is only adapted for functions. So, even if the code would be able to compile, configure fails to detect the macro, causing it to be ignored when compiling the code with OpenSSL from 0.9.8 to 1.0.2. The code needs a configure check as per a364dfa, which has fixed a compilation issue with a past version of LibreSSL in NetBSD 5.1. On HEAD, just remove the configure check as the last release of NetBSD 5 is from 2014 (and we have no more buildfarm members for it). In 11 and 12, improve the configure logic so as both macros and functions are correctly detected. This makes NetBSD 5 still work on already-released branches, but not for 13 onwards. The patch for HEAD is from me, and Daniel has written the version to use for the back-branches.
