These things are noise. I'll fix them, but they're not the cause of
your problem.

This is the problem: configure is telling the linker to link against
libcrypto in the libressl directory but you have not told the runtime
linker to look there for shared libraries, so your binaries (in this
case, the configure test) fail at runtime.
To fix this you probably want to either:
- add /opt/libressl-2.2.4/lib to /etc/ld.conf or /etc/ld.conf.d/ and
run ldconfig
- remove the .so files from /opt/libressl-2.2.4/lib so that the
linker will pick up the static libcrypto.

That'll help anything that inherits the environment, but anything that
sanitizes its environment (eg sudo) will fail, and the resulting
binaries won't work without the environment variable.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
