Checkin e38e05a85828dac23540cd007df5f20985388afc 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.

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.

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.
