I think the idea was that all of the /com, /lib, /usr, /bin, /etc directories
and their bretheren are currently compiled with the -cpu any switch; and
that it might be nice to have a Domain/OS SR10.2.020 in addition to the
currently available SR10.2 (ie. -cpu any) and the SR10.2.p (ie. -cpu a88k).

Although the system utilities, in general, do not have a lot of floating
point code in them, the 020/030/040 have faster memory addressing modes
than those generated by the -cpu any switch. Using -cpu 3000 when compiling
something like /etc/tcpd just might result in a nice performance boost
for network functions.
