It's certainly correct that we envision each target having an explicit list of viable C++ ABIs to select from.

AIUI Clang has no generic multilib support but it's very patchily supported differently in different per-target drivers.  The Fuchsia target support in the driver has explicit logic about the supported multilibs, which we also use for sanitizer configurations, `-fno-exceptions`, and such.
