committed: make i486 default arch for x86 NetBSD

[Krister Walfridsson]

I have committed the attached patch to make i486 the default arch on 
NetBSD in the same way as for FreeBSD, as 386 CPUs are not supported on 
any maintained version of NetBSD.

Bootstrapped and tested on i386-unknown-netbsdelf6.1

 	* config.gcc (i386-*-netbsd*): Make i486 the default arch on NetBSD.
 	Generally use cpu generic.
