Compiling with USE=berkdb links with libdb; add sys-libs/db to DEPEND in
that case.

Apply patch to dlz configure script to use compiler default library paths
rather than hardcoded paths which may point to 32-bit libraries.

Apply patch to autotool macro for finding OpenSSL libraries to use
pkg-config where possible rather than hardcoded paths which may point to
32-bit libraries.  Fix autotool macro to search for correct library name.

Remove specified OpenSSL root path from configure command-line, as it
inhibits one of the configure patches.
