Extend the multi-lib re-use selection mechanism for RISC-V.

This function will try to re-use multi-lib if they are compatible. Definition of compatible:

• ABI must be the same.
• multi-lib is a subset of current arch, e.g. multi-lib=march=rv32im is a subset of march=rv32imc.
• march that contains atomic extension can't reuse multi-lib that doesn't have atomic, vice versa. e.g. multi-lib=march=rv32im and march=rv32ima are not compatible, because software and hardware atomic operation can't work together correctly.
