bug#9403: [emacs] [./configure error] Emacs hasn't been ported to `powerpc-gnu-linux-uclibc' systems

[Douglas Mencken <dougmencken@gmail.com>]

I got this while building GNU/Emacs.
I supposed it's very portable.
In MACHINES file, I can read that only Yellow Dog distro is supported,
regardless of everything...

Of course, all of the above is just plain *false*.

With the following sed command:
sed -i 's/powerpc\*-\*-linux-gnu\*/powerpc*-*-linux-*/' ./configure.in
I've been able to get working GNU/Emacs, even with Snake game :)

Configured for `powerpc-gnu-linux-uclibc'.
