This is a bug in configure I have been trying to debug lately.  I stared 
at it again and finally found the reason:

The CPU options are configured before the command line options are 
parsed.  This is, of course, wrong.  The following patch works around 
this, but it is not a clean solution IMHO.  Anyone have any better ideas?
