The masks you need to determine machine and architecture from the host id
are in /usr/include/machine/cpu.h for your host, and unader
/usr/include/sun*/cpu.h for other architectures.  For example, I am on a
sun 3 and the files <machine/cpu.h> and <sun3/cpu.h> are identical.  If
you want to know about sun 4's look under /usr/include/sun4/cpu.h.

The mask for the architecture is CPU_ARCH and the mask for the machine
type is CPU_MACH.  It makes sense after a little examination.
