Please help me to fix this error.

Well, it appears that you are referencing a function pointer which has not been defined, pm_overflow_handler, or it is a function that has not been implemented. You need to see which source file (and resulting .o) where this function is implemented and make sure it is linked into the kernel. It is being referenced in the source file arch/blackfin/mach-common/built-in.c (probably), but it likely is not implemented there.
