architecture mismatch maybe? the gdi thing I've seen before I think it
has to do with -ldl missing when openssl is static? libcurl configure
script doesn't really account for static dependencies, afaik it relies
on the pkgconfig to give what's needed

I cross compiled static openssl in ubuntu though and I didn't have a
problem, here is exactly how I did it:

sudo apt-get install mingw-w64 mingw-w64-common mingw-w64-i686-dev
mingw-w64-tools mingw-w64-x86-64-dev
curl --fail --location --remote-name-all \ \ \ \
gpg --verify openssl-1.0.2k.tar.gz.asc
gpg --verify curl-7.53.1.tar.gz.asc
mkdir cross-compile
cd cross-compile
tar xfz ../openssl-1.0.2k.tar.gz
tar xfz ../curl-7.53.1.tar.gz
cd openssl-1.0.2k/
export CROSS_COMPILE="x86_64-w64-mingw32-"
./Configure mingw64 no-asm no-shared --openssldir=$PWD/../mingw64/ssl
make depend
make install
cd ../curl-7.53.1/
./configure --host=x86_64-w64-mingw32 --disable-shared --disable-ldap
--without-librtmp --with-ssl=$PWD/../mingw64/ssl
make install

That should put a standalone 64-bit curl.exe in mingw64/curl/bin
