ptrace_machdep.o(.text+0xb): In function `cpu_ptrace':
: undefined reference to `cpu_fxsr'
*** Error code 1

Stop in /usr/obj/usr/src/sys/SOEKRIS.
*** Error code 1

This seems to be related to the new ptrace_machdep.c file.  All other
references to cpu_fxsr I can find are wrapped by #ifdef CPU_ENABLE_SSE

I'm going to try the following and see if it helps here...
