Newlib on a no-os 8260 PowerPC platform

[Likely, Grant]

I've got a 8260 PowerPC platform that I'm trying to get newlib up on.  I've
already brought it up on a coldfire board and I'm comparing the crt0.S that
I'm using for the coldfire with the sim-crt0.S that I'm using as my starting
point for the 8260 board.  (I found the sim-crt0.S in the rs6000 dir of
libgloss)

The coldfire crt0 calls some initialization sections (__INIT_SECTION__), but
the powerpc one does not.  Is there any initialization code that I need to
be calling to setup newlib before jumping into main()?

Thanks,
g.
