illumos gate

Considering the nature of the change, I tested it with wsdiff(1) against a vanilla build.
Here are the results:

Old proto area: /ws/builds/il13602/proto.orig/
New proto area: /ws/builds/il13602/proto/
Results file: wsdiff.out

ERROR: diff_ctf: Could not find genunix. CTF diffs will be less useful.
