[sudo] configure --host=i386

[Sean Bruno]

I was trying to cross compile sudo for i386 on an amd64 host and was
befuddled by the following ./configure error output.

checking for library containing crypt... -lcrypt
checking for library containing getspnam... no
checking for library containing getprpwnam... no
configure: error: "dlopen present but libtool doesn't appear to support
your platform."


I've tried this on 7,8,9 and head with the same result.  Thoughts?
