bootstrap/8146: gcc 3.2 miscompiles gcc 2.95.3

[Janis Johnson]

I tried this (bootstrapping GCC 2.95.3) with 3.2 that I built from a
release tarball and with the 3.2 branch updated an hour or so ago, and
with both of them I get the same bootstrap comparison failures that
were reported in the PR:

  Bootstrap comparison failure!
  cccp.o differs
  f/data.o differs
  f/target.o differs

This was on i686-pc-linux-gnu, with an old Caldera distribution plus
binutils 2.12.1.
