fix #18243

All mainstream distros support the RVA20U64 profile (which defines the ABI) targeting the RV64GC ISA (no optional extensions). This can serve as a baseline for riscv64.

Optional extensions and/or later profiles shall go through a PEP (same status as on x86_64 for v2/v3/v4 ISA extensions).

The vocabulary used here needs to be confirmed by RISC-V experts (cc @markdryan).

All mainstream distros support the `RVA20U64` profile (which defines the ABI) targeting the `RV64GC` ISA (no optional extensions). This can serve as a baseline for `riscv64`.

Optional extensions and/or later profiles shall go through a PEP (same status as on x86_64 fo v2/v3/v4 ISA extensions).
