    sort: Const correctness for C23
    
    On some platforms, e.g. Linux Clang 22.1.8 / glibc 2.43, strchr()
    now implements the C23 behaviour where passing a const pointer to
    strchr() also returns a const pointer.  This breaks sort during
    the bootstrap build, since it assumes the return value is always
    a mutable pointer.
    
    As the returned pointer is never used to modify the value, fix this
    by making the temporary variable const.
