testing consistency

[Jim Wilson]

OK, everyone has agreed now that requiring people to use --prefix=/usr instead
of defaulting it is OK for linux.

I have checked in the following patch to eliminate places that were already
doing this.

	* configure.in (native_prefix): Delete.
	(mips-dec-netbsd): Don't set prefix.
	(*linux*): Don't set prefix.

Index: configure.in
