nixpkgs/pkgs/development/compilers/rust/0001-Allow-getting-no_std-from-the-config-file.patch
Alyssa Ross dc3c338e29 rustc: 1.41.0 -> 1.42.0
The patch is included in rust master[1], but neither that, nor the
QuiltOS version we were using previously, apply to 1.42.0, so I've
included the fixed version here.

Subject: [PATCH] Allow getting `no_std` from the config file
Currently, it is only set correctly in the sanity checking implicit
default fallback code. Having a config file at all will for force
`no_std = false`.
