My Windows builds are built this way, and it has worked fine for many
releases. My makefile is available from:
http://josefsson.org/gnutls4win/Makefile
It uses libgcrypt though, not OpenSSL.

Libtool should work fine for cross-compilation if the environment is
sane.

Put /opt/crosscompilers/win32/bin/ in your PATH instead, and remove the
CC= parameter. Configure should figure out by itself how to invoke the
C compiler for the cross-compilation requested by --build and --host.
However, I suspect your problem is the libssl library. Did you build it
yourself? Do you have a shared build available? The error message
above indicate libtool cannot find libssl.
