Do you have an output/host/usr/lib/erlang/lib/crypto-3.3/priv/lib
directory with a couple shared libraries in it? I assume not based on
the failure, but wanted to check.

Also, does the log from Erlang's ./configure provide any clues?

FWIW, everything that you're doing sounds good to me. I've only seen
the "crypto" undef error on targets when I've forgotten to enable
openssl. I've never seen it on the host, but my host has a lot of
header files, so it's probably not a good test.
