    libgomp: Add -Wno-c-binding-type for omp_lib.f90 compilation
    
    Silence the overeager "Warning: Variable 'depobj_list' at (1) is a dummy
    argument of the BIND(C) procedure ... but may not be C interoperable
    [-Wc-binding-type]" when compiling omp_lib.f90(.in).
    
    The argument is of integer kind 'omp_depend_kind = @OMP_DEPEND_KIND@'.
    
    libgomp/ChangeLog:
    
            * Makefile.am (%.mod): Add -Wno-c-binding-type.
            * Makefile.in: Regenerate.
