H. Peter Anvin 97fc0555da x86 setup: handle more than 8 CPU flag words
Checkin e38e05a858 added a 9th CPU flag
word, but didn't adjust the boot code to match.  This patch adds the
necessary boot code support.

Note: due to a typo in an #if statement, it didn't trigger the #error
this was supposed to do.
