* kern/i386/ieee1275/startup.S (_start): Jump to grub_main() instead of
cmain().
* kern/powerpc/ieee1275/crt0.S (_start): Likewise.
* kern/ieee1275/cmain.c (cmain): Rename to ...
* kern/ieee1275/cmain.c (grub_ieee1275_init): ... this.
* kern/ieee1275/init.c (grub_machine_init): Call grub_ieee1275_init()
