b-f 3.0.9 probably broken for powerpc/pmac

[Richard Hirst <rhirst@linuxcare.com>]

This change to rescue.sh


-if [ "$arch" = hppa -o "$arch" = powerpc -a "$subarch" = pmac ]; then
+if [ "$arch" = hppa -o "$arch" = powerpc -a "$subarch" = pmac -o "$arch" = "mipsel" ]; then
     info "compressing and installing kernel 'linux$subarch'"
-    gzip -9f linux$subarch
-    cp linux$subarch.gz $mnt/linux.gz
+    # gzip -9f linux$subarch
+    # cp linux$subarch.gz $mnt/linux.gz
+    gzip -9cf linux$subarch > $mnt/linux.gz
 else

broke hppa, as release.sh expected to find linux$subarch.gz.  I've fixed
that in release.sh for hppa, but I suspect it also broke pmac.  For pmac
release.sh says

  if [ -f linuxpmac.gz ]; then zcat linuxpmac.gz > $release/powermac/linux; fi

so I guess it will silently fail to produce $release/powermac/linux.
