However, I don't really see how this flag gets set. Doing a 'grep -RH CONFIG_SSE' points to the two makefile includes that add the enable_sse code, but no references to setting the flag.
Such flags are set in Kconfig, and there the CONFIG_ prefix isn't used.
See for example src/cpu/intel/model_6ex/Kconfig. It has "select SSE2", which enables CONFIG_SSE2 for that CPU.
