x96 cannot build without MULTIPROCESSOR

[Emmanuel Dreyfus <manu%netbsd.org@localhost>]

Hi

In -current, x86 seems to be unable to build withotu MUTLIPROCESSOR:
src/sys/kern/kern_stub.c:195:5: error: #error __HAVE_PREEMPTION requires MULTIPROCESSOR

__HAVE_PREEMPTION is defined uncondtionaly in src/sys/x86/include/intr.h

Disabling SMP can be useful, sometime you get a computer model where 
it crashes. The only workaround I see is to build with 
MEMORY_DISK_RBFLAGS=0x10000000	# RB_AUTOBOOT | RB_MD1
