Seems good to me on Ubuntu; builds with both flavors.

From peering at the Windows side:

So to check understanding: the `openssl` config variable is still alive
for MSVC builds; it just turns that into `--with-ssl=openssl` in the
fake CONFIGURE_ARGS?

<bikeshed color="lightblue">

Since SSL is an obsolete term, and the choice of OpenSSL vs NSS vs
[nothing] affects server operation (such as cryptohash) regardless of
whether or not connection-level TLS is actually used, what would you
all think about naming this option --with-crypto? I.e.

    --with-crypto=openssl
    --with-crypto=nss
