I've upgraded to NetBSD 1.1 on our uVAX-II by recompiling (what fun!)
and I found that my recompiled `make' didn't know what MACHINE_ARCH
should be.  This is because machine/param.h doesn't define it, so
here's a patch; apply in /usr/src/sys/arch/vax/include and make
should work without `setenv MACHINE_ARCH vax' first.
