Description
Read the target architecture, as if via readelf -A for a compiled binary from the target, without producing any build artifacts on the host, and print the output as JSON so that the target info can be verified. The Tag_ prefixes should also be removed. This could be useful to prevent issues like #426 when adding new targets.
The output for arm-unknown-linux-gnueabihf would therefore look like:
