    RISC-V: Support -misa-spec for arch-canonicalize and multilib-generator.
[PR104853]

    We migrate the default ISA spec version from 2.2 to 20191213, but those
scripts
    aren't updated at the same time, this patch is making both scripts support
    different ISA spec versions.

    gcc/ChangeLog:

            PR target/104853
            * config.gcc: Pass -misa-spec to arch-canonicalize and
            multilib-generator.
            * config/riscv/arch-canonicalize: Adding -misa-spec option.
            (SUPPORTED_ISA_SPEC): New.
            (arch_canonicalize): New argument `isa_spec`.
