Have a look at target/generic/device_table.txt and
target/generic/mini_device_table.txt.
You define by the buildroot config which file is used to generate the
targets device table.

The problem had gone away after I add udev to the packages.  I am not
sure whether the absence of udev is really the reason that cause the
previous "can't open /dev/tty?" problems.

But I still like to know what you mentioned 'device table'. I want to
ask, what is and where is the 'device table'?  I dont find the
concepts in buildroot on-line doucments.  Thanks.

Yes, you are right. I did not notice it at first time.  But it was
corrected.

You may see in my another post, I now can get the login prompt, and my
problem switchs to "Why I can not login". I hope I can get your help
in that thread.
