Is it necessary to reuse AT_FLAGS?  I think it's cleaner to define a
separate AT_ tag dedicated to binfmt_misc.

Not necessary, but it seemed simpler and cleaner to re-use a flag that
is marked as unused and with a name matching the new role. It avoids to
patch other packages (like glibc) to add it as it is already defined.

Thanks,
