nds32: fix build error "relocation truncated to fit: R_NDS32_25_PCREL_RELA" when
make allyesconfig
It will cause a linking error because the jump assembly code were using j,
however it may be not enough to jump to the destination. We have to change it
with pseudo instruction b. In that way, assembler will generate a set of safe
assembly codes to make sure the destination is able to jump.
