MinGW Cross-Compiling results in error "ld: cannot find -link"

Hello,

I'm trying to build libcurl for Windows using Ubuntu's 'mingw-w64'
package. Since I'm building from the git repository, and the CMake
script has a message stating that it is poorly maintained, I wanted to
build it through configure with make. As there is no configure file in
the git repo, I made one using:

> git reset --hard
> git clean -fdx
> autoreconf -i
And then configured it with:
> ./configure --prefix=$_SYSROOT --host=x86_64-w64-mingw32 --with-gnu-ld
> --with-pic --disable-debug --enable-optimize --disable-curldebug
> --disable-dependency-tracking --enable-shared --enable-static
> --enable-http --enable-ftp --enable-file --enable-proxy --enable-ipv6
> --enable-threaded-resolver --enable-pthreads --enable-sspi
> --enable-crypto-auth --enable-tls-srp --enable-http-auth
> --enable-cookies --enable-doh --enable-mime --enable-progress-meter
> --enable-dnsshuffle --disable-ldap --disable-ldaps --disable-rtsp
> --disable-dict --disable-telnet --disable-tftp --disable-pop3
> --disable-imap --disable-smb --disable-smtp --disable-gopher
> --disable-manual --disable-versioned-symbols --disable-unix-sockets
> --disable-dateparse --disable-netrc --disable-alt-svc --without-ssl
> --with-sysroot=$_SYSROOT --withzlib=$_SYSROOT --with-mbedtls=$_SYSROOT
It configures fine, but for an unknown reason a sed command is added to
the linker command which replaces all '-lLIBRARY' with '-link LIBRARY',
and it seems impossible to remove. Removing the
'--host=x86_64-w64-mingw32' makes it link, but then fails that it
couldn't find libcurl.so (as the cross compile toolchain produces .dll
files). The command that breaks is:

I think the problem is the --host= value, but what would be the correct
value for it? I tried mingw64-win32 but it just gave the same result as
x86_64-w64-mingw32.
