Replying to an old thread, but FYI this problem which has been bugging
me since months has gone away since the lastest clang
branches/release_30 import, and it has been MFC'ed to stable/9. I can
now buildworld with -march=3Dcorei7 instead of -march=3Dcore2 :) (the same
should apply for -march=3Dnative)

Cheers
