// FIXME: "none" triples get a placeholder SDK/platform and don't support any specific triple by default. Unlike most platforms, where the vendor and environment is implied as a function of the arch and "platform", bare metal operates in terms of triples directly. We need to replace this bringup convenience with a more idiomatic mechanism, perhaps in the build request.
