cc #103541

[Enselic]

Triage: Can you still reproduce? This passes for me now with:

./x test tests/run-make/fmt-write-bloat

on x86_64-unknown-linux-gnu which uses lld by default.

[jieyouxu]

Please lmw if this still fails with #128147? We ran the rmake.rs version through several try jobs and they didn't fail (AFAIK this should be using lld on linux-gnu since the default changed).

[saethlin]

No new complaints, and I can confirm I have had no issues from this test locally when using lld.
