Based on copy from microblaze add ucmpdi2 implementation. This fixes build of niu driver which failed with: drivers/built-in.o: In function `niu_get_nfc': niu.c:(.text+0x91494): undefined reference to `__ucmpdi2' This driver will never be used on a sparc32 system, but patch added to fix build breakage with all*config builds.
