Subject: [PATCH] add-cros-targets

Because of b/187783596, armv7 target triple's arch and ABI parts
differ between chromeos and rust. Until that bug is fixed, we have to
add our own triple for armv7.

Additionally, the Rust compiler does not implement a fallback for unknown
target triple vendors (e.g. "cros" or "pc") to the "unknown" variant, so we
add copies of the relevant cros targets here as well.
