On Solaris/x86 MACHINE is sunos5.i86pc and MACHINE_ARCH is i86pc (both
determined in

Is MACHINE_ARCH supposed to be constant on an operating system across
different machines if they use the same processor family (eg, x86 and
compatibles) ? Solaris seems to do this, as far as I know MACHINE_ARCH
is always "i86pc" (output of "arch" or "uname -m") independant of
specific CPU (Pentium, P II, P III, AMD...) and number of processors.
