    gnu: Disable compressed debug sections for mingw-w64
    
    The newly introduced --enable-compressed-debug-section=all configure
    flag in the base binutils package makes the mingw-w64 build system
    unusable. For example:
    
        $ guix build --target=x86_64-w64-mingw32 hello
    
            and
    
        $ guix build mingw-w64-x86_64-winpthreads
    
    Will fail to build with an error:
    
        "x86_64-w64-mingw32-ld: final link failed: bad value"
    
    Turning off this flag seems to fix the problem, but perhaps it'd also be
    worthwhile to investigate the root cause.
    
    * gnu/packages/cross-base.scm (cross-binutils): When building for mingw
      targets, append "--enable-compressed-debug-section=no" to configure
      flags.
