[PATCH v2] Make *-netbsd mean ELF rather than a.out for all CPU archs, deprecate ns32k-netbsd

[Nick Clifton]

Hi John,

> As discussed previously, a.out support is now quite deprecated, and in
> some cases removed, in both Binutils itself and NetBSD, so this legacy
> default makes little sense. `netbsdelf*` and `netbsdaout*` still work
> allowing the user to be explicit about there choice. Additionally, the
> configure script warns about the change as Nick Clifton requested.

Patch approved and applied.  (Sorry for the delay - I was on holiday).

Cheers
