I barely dare to report what I've found by now...

FWIW, my compilation machine still runs IRIX 6.5.9, but another is
upgraded to IRIX 6.5.15.  Since the code mentions IRIX 6.5.14 in some
place, I thought it might be a good idea to try to compile on 6.5.15
(same gcc binary, NFS mounted from my 6.5.9 machine).

The results are:

- dumping (as compared to compiling/linking) an unmodified emacs 21.2
  on my IRIX 6.5.15 works (even when running the resulting binary on
  IRIX 6.5.9).  It makes no difference whether the compilation
  directory is NFS-mounted or local.

- dumping (as compared to compiling/linking) an unmodified emacs 21.2
  on my IRIX 6.5.9 does not work (even when running the resulting
  binary on 6.5.15).  It makes no difference whether the compilation
  directory is NFS-mounted or local.

So it seems the dump process (not the compilation or the linking of
`temacs') is the crucial step which requires the correct runtime
libraries of IRIX (?).  I ensured that the only shared libraries are
SGI libraries, everything else (libz, libpng and libtiff) is
statically linked (same versions on both machines).

Since the maintenance versions of IRIX are available free, I think it
would be a good idea to mention this in the PROBLEMS file.
