I dont notice this issue one week before (I update my coreboot source code one a week), does anyone have the same issue?
There weren't any issues in the area I'd suspect would be responsible (src/arch/x86/Makefile.inc).
You could try to use git bisect (see http://git-scm.com/book/en/Git-Tools-Debugging-with-Git#Binary-Search) to pin down the revision that introduced the broken behaviour.
