[MIPS] Rename CONFIG_BUILD_ELF64 into KBUILD_64BIT_SYM32
This patch renames it for 3 reasons:
- "CONFIG" pattern is used by Kconfig. Now this macro is
no more defined by Kconfig but by Kbuild itself make this
clear by translating "CONFIG" into "KBUILD".
- "ELF32" word is improper because it is irrelevant to ELF
format and it makes confusion with CONFIG_BOOT_ELF32. So
translate it with SYM32.
- Add "64BIT" part to make clear that this macro implies a
64 bits kernel.
