MXE cross-build distribution problem with octave-gui.exe

[Rik]

1/3/14

When trying to create a zip file of the MXE distribution I use './mk-dist
--stable' (no installer, just zip file).  There seems to be a race
condition somewhere in the script because I get the following output:

rik:~/wip/Projects_Mine/mxe-octave: ./mk-dist --stable

  octave and dependencies...
tar: ./bin/octave-gui.exe: File removed before we read it
  octaverc file...
  native tools...

And indeed, there is no octave-gui.exe in the bin directory of the
resulting zip file.

Along the same lines, the dist/ directory is created and under it is the
directory octave-3.8.0.  However, the zip file contains the full path
/home/rik/xxx/yyy/zzz/dist/octave-3.8.0.  This is annoying as I have to
unpack the zip file on the Windows side and then hunt for octave-3.8.0 and
bring it back up 5 or 6 directory levels.  The changeset that introduced
this was 3387:0779856e1186.
