RISC-V: Lookup reversely in riscv_select_multilib_by_abi
When use --print-multi-os-dir or -print-multi-directory, gcc outputs
different values with full -march option and the base one only.
$ ./gcc/xgcc --print-multi-os-dir -mabi=lp64d -march=rv64gc
lib64/lp64d
$ ./gcc/xgcc --print-multi-os-dir -mabi=lp64d -march=rv64gc_zba
.
The reason is that in multilib.h, the fallback value of multilib
is listed as the 1st one in `multilib_raw[]`.
gcc
* common/config/riscv/riscv-common.cc(riscv_select_multilib_by_abi):
look up reversely as the fallback path is listed as the 1st one.
