I think it is only used to detect if the compiler/assembler is knows those instruction. i.e. an old compiler might not know AVX instructions Bad example since we aren't even testing that in configure. gcc is to blame for it since it doesn't fail with -march=nocona -mno-sse4 on SSE4 instructions in inline asm statements.
