ARM: 9470/1: Handle BE8 vs BE32 in ARCH_CC_CAN_LINK

ARM: 9470/1: Handle BE8 vs BE32 in ARCH_CC_CAN_LINK

ARM big-endian has two different binary formats. BE8 and the older BE32.
They are incompatible with each other.

Handle those when evaluating ARCH_CC_CAN_LINK by using the respective
configuration of the kernel itself.
