klibc - Nov 2003 - [PATCH] update crt0.S on ppc32

The _start stuff was changed some time ago, but ppc was not updated.
This fixes klibc for me. I'm not sure what to do with the second arg to
__libc_init, so I set it to 0..

However, looking at other static binaries, there is more stuff todo.

You need to look at the psABI for the target platform (I don't have the 
one for PPC) to find out how to get the onexit pointer.  However, it's 
not a huge deal, as I believe Linux always makes it zero.  You want to 
at least put in a comment to that effect, though.
