riscv: Use memcpy to handle unaligned access when fixing R_RISCV_RELATIVE
Although RISC-V Linux will enable the unaligned memory access handler by default, that is quite expensive in general, using memcpy will be much cheaper - just break down that into several load/store byte instructions. ARM and MIPS has similar issue: ARM: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51456 MIPS: https://gcc.gnu.org/legacy-ml/gcc-help/2005-07/msg00325.html Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
