Alternatively you could omit the -Clinker-flavor arg entirely on wasm given that wasm already uses lld by default (there is no other wasm linker that I know of).

We should use -Zlinker-features instead of the flavor, I messed this up. I fixed it in #139378.
LinkerFlavor::WasmLld is the only supported link flavor for wasm.

To provide a bit more context; I would really like to avoid hardcoding any flavors in bootstrap, that's fragile and flavors might be removed in the future anyway. With Thank you for looking into this though, and for reporting the issue! |
Rollup merge of rust-lang#139378 - Kobzol:bootstrap-use-lld-fix, r=petrochenkov Use target-agnostic LLD flags in bootstrap for `use-lld` [Before](rust-lang#135001), I hardcoded LLD flags that pretty much only worked on GNU. The right way is to use `-Zlinker-features` instead though. I *think* that this should also make this work on Windows mingw, and thus `@petrochenkov's` workaround is no longer necessary.
