This is a 'string' option, so defaults should be enclosed between
double-quotes:
default "arm600" if BR2_ARM600
Ditto for all archs.
Yep, that's how the code was prior to your changes, but why not clean it

If you fix that in this patch, or in a following patch:
Acked-by: "Yann E. MORIN" <yann.morin.1998 at free.fr>
