Subject: Flag day: Updated bfu required for performance counters on AMD (Addendum)

On existing workspaces where you pull in this change, a cleanup of your
proto area (or clobber build) is required to avoid the following errors
during an incremental build...

==== cpio archives build errors (non-DEBUG) ====

Failed to create generic usr archive:	486540 blocks

Sorry for the inconvenience.

Thanks to James McPherson for pointing this out.
