+configure: use pkg-config to find openssl
+
+The current check is broken for static linking, since the openssl
+libs need to be linked against libz, which is missing in the link
+command when doing a static build:
+    http://autobuild.buildroot.net/results/787/787cd9992b00d8008641af208f5fb7c4afb40b06/build-end.log
+
+Instead of trying convoluted tests to decide what additional libs
+are required, just delegate this job to pkg-config.
+
+At the same time, fix a few legacy, deprecated constructs in favour
+of their new counterparts.
