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.
