>Description:
LKM compat_freebsd.o is not loadable.

Errors:
# modload /usr/lkm/compat_freebsd.o
/usr/lkm/compat_freebsd.o(.data+0x9a0): undefined reference to `freebsd_sys_sysctl'
/usr/lkm/compat_freebsd.o(.data+0xf34): undefined reference to `freebsd_sys_yield'

modload: can't prelink `/usr/lkm/compat_freebsd.o' creating `/usr/lkm/compat_freebsd'

>How-To-Repeat:
1. Build kernel with 'no options COMPAT_FREEBSD'
2. modload /usr/lkm/compat_freebsd.o

>Fix:
Add freebsd_sched.c and freebsd_sysctl.c in Makefile.
