Clarify .arch_extension possible values

Documentation for .arch_extension says it accepts the same architectural
extensions as those accepted by -mcpu. Given the name and the fact that
-march for obvious reason also accept the same extensions, I believe
it's worth mentioning that it accepts the same extensions as both
-march and -mcpu. This commit addresses that.
