It's especially notable if not only the glibc-based Linux configurations, but musl, android, etc. are also still doing `-fshort-enum` / `aapcs-linux` then there is no question that Fuchsia wants to follow them all.  If e.g. Android differed from `-gnueabihf` on this then we might consider whether to align with one or the other.
