s390: Implement ARCH_HAS_CC_CAN_LINK

The generic CC_CAN_LINK detection relies on -m32/-m64 compiler flags.
Some s390 toolchains use -m31 instead but that is not supported in the
kernel.

Make the logic easier to understand and allow the simplification of the
generic CC_CAN_LINK by using a tailored implementation.
