Thou shalt not leak build host state into the system being compiled.

The VERSION variable is encoded into the SUNW_ctf sections of the kernel
and every kernel module when dtrace is enabled; starting with 9.2-RELEASE
(when dtrace was turned on in GENERIC) this means that different host kernels
will result in very different kernel binaries being generated.  This tripped
up freebsd-update builds after the build boxes were updated from 9.x to 10.x.
