FYI, ZX1 config problem in 2.4.23/2.4.24

[Bjorn Helgaas]

When I changed the "HP-zx1" kernel config choice to just "HP",
I seem to have exposed an oddity in the way menuconfig works.
The menu contains this:

        "generic                CONFIG_IA64_GENERIC             \
         DIG-compliant          CONFIG_IA64_DIG                 \
         HP-simulator           CONFIG_IA64_HP_SIM              \
         HP                     CONFIG_IA64_HP_ZX1              \
         SGI-SN2                CONFIG_IA64_SGI_SN2" generic

and apparently when the user selects "HP", menuconfig turns on
the *simulator* symbol (CONFIG_IA64_HP_SIM) instead of the HP_ZX1
symbol.  I think this looks like a menuconfig bug, but the easiest
way around it is probably to use a patch like this:

One symptom of this problem are messages like this when linking
the kernel:

I think another way to do it would be to move HP_ZX1 above HP_SIM.
But aesthetically, we should probably put the simulator option down at
the bottom anyway.
