-Subject: [PATCH] Allow getting `no_std` from the config file

-# New rust versions should first go to staging.
-# Things to check after updating:
-# 1. Rustc should produce rust binaries on x86_64-linux, aarch64-linux and x86_64-darwin:
-#    i.e. nix-shell -p fd or @GrahamcOfBorg build fd on github
-#    This testing can be also done by other volunteers as part of the pull
-#    request review, in case platforms cannot be covered.
-# 2. The LLVM version used for building should match with rust upstream.
-# 3. Firefox and Thunderbird should still build on x86_64-linux.
