* 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. * include/grub/i386/pc/kernel.h (grub_kernel_image_size): Removed. * include/grub/i386/qemu/kernel.h (grub_kernel_image_size): Removed.
