    I just ran into this issue trying to build in Arch using the lld strategy (e.g. not Docker/cross). I'm trying to compile steed itself, not a dependent crate.
Note: The redox issue linked seems to be closed. So I'm assuming we still need to use naive_ralloc.
I edited Xargo.toml per this discussion, but it didn't quite work.
[dependencies]
collections = {}
rand = {}

[dependencies.std]
default-features = false
features = ["naive_ralloc"]

[dependencies.compiler_builtins]
features = ["mem"]
stage = 1
That config still yielded a similar error
error: Package `ralloc v1.0.0 (https://github.com/redox-os/ralloc#
b521bac2)` does not have these features: `allocator`

Instead I fiddled with Cargo.toml, to try building with naive_alloc.
[package]
# This is NOT an official Rust project but since most code will come from
# the rust-lang/rust repo it makes sense to use this author.
authors = ["The Rust Project Developers"]
name = "std"
version = "0.1.0"

[dependencies]
sc = "0.2.1"

[dependencies.ralloc]
default-features = false
features = ["allocator"]
optional = true
git = "https://github.com/redox-os/ralloc"

[dependencies.naive_ralloc]
optional = true
path = "naive_ralloc"

[features]
default = ["naive_ralloc"]

[profile.release]
lto = true
Then I tried building with
xargo build 

The output
error: failed to load source for a dependency on `collections`

note: run with `RUST_BACKTRACE=1` for a backtrace

I'm not quite sure how to get past this compiler error.
