I tried that, but that's not the only thing required. Because the Kconfig default the ISA is ISA_ARCOMPACT, allnoconfig uses that, no matter what the default in the Makefile is. And, since tinyconfig is based on allnoconfig, it has the same problem. I submitted a patch[1] that gets this working for me, and with that, 'make defconfig', 'make allnoconfig' and 'make tinyconfig' all work with ARCv2 by default.
