# --with-openssldir is a dirty hack to find a cert bundle at runtime. libressl
# assumes "cert.pem" under openssldir, but eg. Debian's cert bundles instead
# live in /etc/ssl/certs/ca-certificates.crt, so while this hack means that
# relocating the source directory requires rebuilding libressl, this is still
# easier than finding the system cert bundle and patching libtls with its
# location.
