Can you share a bit more about the use cases? Does setting `CC_arm_unknown_linux_gnueabi=arm-none-linux-gnueabi-cc` not suffice? Specifically for `arm-none-linux-gnueabi`, it might be best to change `prefix_for_target` to use `find_working_gnu_prefix` for `arm-unknown-linux-gnueabihf`...

Hi! Is this cargo feature documented anywhere? The [docs](https://doc.rust-lang.org/cargo/reference/build-scripts.html#rustc-link-lib) only shows the `=[KIND=]NAME` syntax, but say nothing about any modifiers.

> This is a rustc syntax (https://doc.rust-lang.org/nightly/rustc/command-line-arguments.html#-l-link-the-generated-crate-to-a-native-library), cargo just passes the `STRING` in `cargo:rustc-link-lib=STRING` directly to rustc. Ah great. Can you add a link to that in the doc comment...

At least on Arch Linux, the `musl` package for x86-64 contains `musl-gcc`, but not `x86_64-linux-musl-cc`.

I suppose `+soft-float` would be used when compiling kernel code that shouldn't touch floating point registers. Not sure of all the other use cases though. In any case, silently producing...

I vaguely remember this is on purpose, because `zshenv` was not loaded in all cases or something like that. (`.profile` is also idempotent on purpose.) @de-vri-es do you remember why...

Ah, looks like I did that. Explanation in commit 61362aefc88dc5fb2b82b12a66191b4eef457265: ``` commit 61362aefc88dc5fb2b82b12a66191b4eef457265 Author: Mara Bos Date: Sat Jul 8 15:58:22 2017 +0200 Source .profile in zshrc as well. For...
