Try the current tip.  Some files got moved around when Linux support was
added.  I did a clean pull and it built fine.

The dynamic PCRs are set to all Fs on platform reset and only get
cleared to 0s on initiation of a DRTM (e.g. SENTER).  So if they are
really not 0s before being extended then that would mean that the SENTER
failed.  And the code should not even try to extend them if SENTER
fails.

The policy format has changed as of a month or so ago and the policy
code got a lot of cleanup.  Try with the current tip.
