Wouldn't i486 be more conservative?

Really, given this change, I think sysdeps/i386/i486 should be merged into 
sysdeps/i386, and likewise for nptl/sysdeps/i386/i486 and 
nptl/sysdeps/unix/sysv/linux/i386/i486, since i486 will be the minimum 
supported x86 processor.  Given that, there would be no real point setting 
machine to i486 since there wouldn't be i486 sysdeps directories any more.  
If you don't do that followup moving of files, it should at least go on 
the wiki / Bugzilla as a todo item.
