Thanks for your reply, I had compiled succeed on a ubuntu10.04 PC. But I still want to know whether it is a seabios bug.
I also found some messages on google, one of those mentioned:

"Just checked with the latest 2.21 snapshot, works fine."

It means that binutils version is the reason, but my version is 2.21. : (
