Thinking about this overnight and discussing with some colleagues, we've
concluded that the best generic default is probably ARM7TDMI, since
StrongArm is now on the deprecated list (note, not obsolete - yet) as it
lacks support for Thumb. Because of this I've changed the NetBSD
default to StrongARM as that reflects that this target can still support
ARMv4 devices.
So I've committed this patch:
PR target/86383
* config.gcc (arm*-*-netbsdelf*): Default to StrongARM if no CPU
specified to configure.
(arm*-*-*): Use ARM7TDMI as the target CPU if no default provided.
R.
