The advantage of this approach is that as soon as upstream gcc
supports the microblaze or arc architecture, the only change required
is to remove depends on !BR2_microblaze or !BR2_arc for that release.

I understand. See below for a possible fix. Let me know if you think
this is better.

instead of above do something like
-else ifeq ($(BR2_arc),y)
+else ifeq (BR2_GCC_VERSION_4_8_ARC,y)

Also, updating the AVR32 code to work in the same manner would probably be best.
Thanks,
