    update-alternatives.bbclass: Disable for mingw32 targets
    
    When building for mingw32 targets (e.g. nativesdk cross compiling for
    windows), disable the dependency on update-alternatives as the Windows
    platform does not support symlinks or package management.
    
    This avoids the complex (partly non-buildable for mingw32) dependency
    chain virtual/update-alternatives -> opkg-utils -> python -> ...
