	AIX 3 is POWER architecture, but AIX 4 uses common-mode with only
the subset of instructions common to both POWER and PowerPC architecture,
along with calls to absolute functions at low addresses supplied by the
kernel to handle integer multiply, divide, and quotient.  Some early IBM
members of the Linux/PPC group already looked at this and had a plan to
provide compatibility and supply the exported AIX kernel symbols for system
calls.
