* grub-core/kern/i386/coreboot/init.c (grub_machine_init): Use
_edata and _start.
* grub-core/kern/i386/coreboot/startup.S: Move multiboot header after
the small code. It moves it only by few bytes but simplifies the code.
* grub-core/kern/i386/pc/init.c (grub_machine_init): Use _edata and
_start.
* grub-core/kern/i386/pc/startup.S: Use _edata and _start.
(grub_kernel_image_size): Removed.
* grub-core/kern/i386/qemu/startup.S: Use _edata and _start.
(grub_kernel_image_size): Removed.
[APPLE_CC]: Remove apple compiler support. i386-qemu port can't be
compiled with Apple toolchain.
* grub-core/kern/sparc64/ieee1275/crt0.S: Remove leftover fields.
