Failure to compile OpenSSH.

libz is installed where RedHat puts it, i.e. /usr/lib.

Since this is with gcc, I tried with LDFLAGS="-static"

./configure --with-ssl-dir=/afs/biocenter.helsinki.fi/v/@sys/libraries/openssl/latest

fails the same way. dso_dlfcn.o in OpenSSL libcrypto.a refers to the
undefined functions dlopen, dlclose, dlsym.

Explicitly including -ldl in LDFLAGS allowed configure to finish
properly (without -static in LDFLAGS, I should probably add).

Now, the build fails, with the following error messages:
