emacs: added version 23.1 and fixed compilation on x86

The main advantage in this version is that the handling of fonts is a
    lot better:
    In emacs-x11 the used fonts are not tiny anymore and can
    easily be chosen

Note that we still use qemu for bytecode compilation on x86,
    that is for several reasons:
  *The most important one is that it prevents using the host's
    libraries
  *It simplifies the recipe(no separate case when the architecture
    is the same )
  *It should work if someone cross-compiles for x86 on
    his mips,arm,powerpc,sparc computer

Warning: emacs_23.1 has not been tested but emacs-x11_23.1 has
    so putting defaullt preference to -2 in emacs_23.1
