[Nut-upsuser] ./configure --with-openssl fails with OpenSSL 1.1, SSL_library_init now a macro

I was unable to run ./configure --with-openssl on Debian Stretch. The
./configure output ends with
checking for OpenSSL version via pkg-config... 1.1.0f found
checking for OpenSSL cflags...
checking for OpenSSL ldflags... -lssl -lcrypto
checking for openssl/ssl.h... yes
checking for SSL_library_init... no
configure: error: "OpenSSL not found, required for SSL support"
The giveaway is that ssl.h which defines SSL_library_init is present, but
configure can't see the symbol SSL_library_init.
As often happens, the folks over at Arch Linux have the technical details, and
the explanation is to be found at https://bugs.archlinux.org/task/53809
[FS#53809 - [libesmtp] Not correctly linked against openssl 1.1] << in openssl
1.1, SSL_library_init is a preprocessor macro, not an actual symbol; so
libesmtp's ./configure erroneously thinks that libssl isn't available, >>
There is a technique for fixing this problem by modifying configure.ac at
but I don't see how to apply it to nut-2.7.4/configure.ac
