added a line that adds -limage to the PF LIBS macro only if you're on IRIX

I tested, and it generated the correct makefile.  I don't think it will
break anything for other OS's...


    dnl # Under Irix users will need -limage to load .flt files
    dnl # referencing .sgi images
    if test "$PLATFORM" = "IRIX" ; then
            _PFOGLLIB="${_PFOGLLIB} -limage"
    fi
