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.

c7d624d1ee x86: Fix up silly i1586 boot message.
Trying to boot a 64-bit kernel on a 32bit Pentium 4 gets
you an amusing message along the lines of.
"you need an x86-64, but you only have an i1586"
due to the P4 being family F.  Munge it to be 686.

f0be6c6a69 x86 setup: print missing CPU features in cleartext
Instead of obscure numbers, print the list of missing CPU features in
cleartext.  To conserve space, use a host program (mkcpustr.c) to
produce a compact list of mandatory features only.
