[PATCH RFC 04/11] readelf: Fix set but not used parameter

[Ilya Leoshkevich]

clang complains:

    readelf.c:12205:72: error: parameter 'desc' set but not used [-Werror,-Wunused-but-set-parameter]
    handle_bit_registers (const Ebl_Register_Location *regloc, const void *desc,
                                                                           ^

Apparently handle_bit_registers() is unimplemented, but one line is
still written for the future. Silence the warning by casting desc to
void.
