Reopened the bug, because I'm still not convinced that the new behaviour of gcc
4.5 is correct.
With gcc 4.4 you have to explicit set arch optimization, usually done via
CFLAGS. If not set there's no optimization.

Ok, thanks, I feared that you would say that. Will try to move the issue to
glibc.
But for now we have the unpleasant situation, that current gcc fails to compile
current glibc if host is set to i686.

Actually I want a i686 configured gcc and gcc should be able to compile glibc
without setting -march to something different, that's how it works with any
older gcc 4.x.
As you can see in my supplied examples, gcc 4.5.0
