I do tend to get this whenever I try to build a full set of kernel from the packaged kernel config. I haven't reproduced it recently though, so I don't know exactly what tool versions are affected. Doing long long divisions anywhere in the kernel is apparently considered wrong, but in this instance it may be a compiler bug that is leaving a stray reference to the division helper in the code: http://thread.gmane.org/gmane.linux.alsa.devel/84361/focus=115079 I don't know if anything has been done about this.
