Fix some TODOs in the yasm build.

The TODO about a system yasm is not longer necessary. We don't need to support this for Chrome developers. For Linux distros, Pawel has added an overlay to change the behavior.

The TODO about the output names is out-of-date. The new output location matches the names generated by the C compiler in the Chrome build.
