Its unlikely the distro will solve your issue. The general recommendation might
be to use gstreamer/cerbero build system, it will setup the environment and pull
a known to work mingw toolchain. Make sure to read the README. Cross-compliation
is hard, cerbero helps avoid most of the common mistakes.
