Avoid aliases when compiling with Apple's CC for PCBIOS machine

	* kern/misc.c [APPLE_CC] (memcpy): new function
	[APPLE_CC] (memmove): likewise
	[APPLE_CC && !GRUB_UTIL] (grub_err_printf): likewise
	(memcpy): define alias conditionaly on !APPLE_CC
	(memset): likewise
	(abort): likewise
	* include/grub/misc.h (memove): don't define when both GRUB_UTIL and
	APPLE_CC are defined
	* include/grub/list.h [APPLE_CC] (grub_assert_fail): new function
	(grub_assert_fail): make prototype conditional
