make 9vx/9vx
will build only 9vx and will not need vx32-gcc.

if you make clean
and then edit the top-level src/Makefrag file to add -m32
to the HOST_CFLAGS and then make 9vx/9vx
you are likely to get a working binary.

compiling in 64-bit mode is almost certainly
not going to work; the plan 9 kernel code is
very 32-bit here.  and it would be very confused
if its own pointers were 64-bit but the user
code pointers were 32-bit.
