Dodgy (hack job) port of find from findutils.

The source is from the GeekGadgets source repository, and is included in this
archive.

Compiled with clib2, not newlib.

This tool, "find", is often needed when compiling some games and libraries, in
order for the Makefile to be able to find files. Examples include Neverball and
libode (without "Find", there is no indication anything has gone wrong, however
you end up with 5 libraries instead of 1).

I believe this is also the reason behind OS4 having vorbis, vorbisfile and
vorbisenc instead of just 1 giant libvorbis. Could be wrong!

Prior to this port, the GeekGadgets "Find" could be used with Joerg's PPC
ixemul.library, but it always caused a DSI error.

Note: "fork" and "wait" code removed. I cannot guarantee the stability or full
compatibility of this port.
