MIPS: kconfig: add options for endianess select
Add new Kconfig option to let the user select the targets endianess. Each target have to select SUPPORTS_BIG_ENDIAN and/or SUPPORTS_LITTLE_ENDIAN to indicate which endianess is supported. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
