Automatically detect cross-compilation case. If you have an i386

(well that is the only tested host environment for the time being)
and would like to test the support, do this:
cd /usr/src
make TARGET=vax
cd sys/arch/vax/conf
config MYKERNEL
cd ../compile/MYKERNEL
make
and you should get a nicely compiled vax kernel.  This is WIP, so do not
expect robustness quite yet.
