Enabling an AutoFDO build requires users to explicitly set CONFIG_AUTOFDO_CLANG.

This patch looks good to me.
I assume the profile format change in the Android doc will be submitted soon.

In the new System.map, we have:
81112400 T _stext
This looks wrong. It should point to the beginning of the text, like
