Tools are not available on cross compiled platforms since #61861 #62558
Description
Moved from rust-lang/rust-clippy#4267
#61861 was merged in #61962, since then Rustfmt fails to build when cross compiling which is the case for almost all non Tier 1 platforms.
Clippy and RLS are failing with similar error.

Why does Clippy depend on rustfmt? We only have it in our Travis tests, and even then a test-fail shouldn't cause an unshipped tool
mati865 commentedon Jul 10, 2019
Modified issue description, it depends on
fmt_macrosbut the error is basically the same.its-pointless commentedon Jul 10, 2019
only way i got it to build cross tools was from example in original post copying librustc_macros-97bf1e9c420f9886.so over librustc_macros-2f4546e1163449fb.so
this and suddenly rust nightly std library doubling in size... fun times.

ping. Any progress here? This issue blocks tier2 users from upgrading past rustc nightly 1.36.0.
Manishearth commentedon Jul 29, 2019
I can't tell where the logs for Clippy on cross platforms are so I don't know how to fix this. Rust has a ton of builders :/
mati865 commentedon Jul 29, 2019
@Manishearth logs for last successful merge: https://dev.azure.com/rust-lang/e71b0ddf-dd27-435a-873c-e30f86eea377/_apis/build/builds/4613/logs/937?&api-version=5.0-preview
It still fails with the same error.
Manishearth commentedon Jul 29, 2019
Hmm that seems like the rust build system being brittle. I've seen that kind of error before, it's usually solved by deleting something in the build dir.

That isn't an issue about stale build directories or anything like that. Something is misconfigured to cause the rustc-macros crate to get built twice. The rustc_macros crate should not be getting compiled into the stage1-tools directory, but something is pulling it in. I haven't investigated to see what, though.
(it'd be good as well btw to not assume default-flakiness and instead assume that because it is a consistent regression that there's something which needs to be investigated)

I think
rustc_macrosare expected to be available in stage1: https://github.com/rust-lang/rust/pull/58013/files#diff-4bc384d35e57dc577b9378d4d733d7c3R818The issue started when
