I have been receiving errors when configuring Stunnel, which I intend to cross compile for use with my Linksys WRT54GL router (Tomato firmware). When passing ./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp the configure process stops with an error.

Here is the complete output.

./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp configure: WARNING: If you wanted to set the --build type, don't use --host.
