I learned one more tips. I had to remember 'summarize' option. Thanks!

You are right. This issue was clearly stated in ext2root.mk as 'Known 
problems'.
Until now, I read ext2root.mk but I noticed it after you  mentioned it. 
What a shame that I did so.
I want to try to make such a script to add the /dev/*  files later.

Thank you for your kindness and advice. With JeeBak and Erik's help,
my question was resolved and I can obtain new, cool development system
against uClibc now.

Again, Thanks. It is very kind of you.
