4.2::SYSV compatability problem

[John Haller]

Try using Mcc rather than cc.  If Mcc doesn't exist, link cc to Mcc,
and do the same for things in /lib.  I suspect that you are running
System V, Release 1, and the third release of that for the 3B5.
The hue and cry complaining about cc being broken in System V
Release 1 came too late for cc to be fixed properly, as it is in
System V, Release 2.  Hence the kludge.
