Bug 29882

fnu# make
linking kernel
mp_machdep.o: In function `ap_init':
mp_machdep.o(.text+0x219c): undefined reference to `enable_sse'
*** Error code 1

Stop in /usr/src/sys/compile/IRANGER.

happens when attempting to use the following config file.

Fix: 

Either conditional compile out the enable_sse call in mp_machdep or pull out the enable_sse routine in initcpu.c from behind the I686_CPU conditional.
