This is based on previous commit ("microblaze: Use simple memset
implementation from lib/string.c") where generic memset implementation is
used when OPT_LIB_FUNCTION is not defined. The same change can be done for
memset/memcpy implementation where doesn't make sense to have generic
implementation in architecture code.

Optimized C library functions can rapidly speedup the kernel.
memset doesn't need to be optimized because there is no difference
in behavior on little/big endian cpu.
