bootstrap requires non-existing src/gcc submodule on static.rust-lang.org tarball #138124
Description
Summary
Hi, I'm a Alpine Linux contributor.
We use the tarball of https://static.rust-lang.org/dist/rustc-$pkgver-src.tar.xz which does not contain the src/gcc submodule added in 9028177.
Since 1.85.0 bootstrap started failing in build_helper:
thread 'main' panicked at src/bootstrap/src/utils/helpers.rs:442:5: std::fs::read_dir(dir) failed with No such file or directory (os error 2) stack backtrace: 0: rust_begin_unwind 1: core::panicking::panic_fmt 2: bootstrap::utils::helpers::dir_is_empty at ./src/bootstrap/src/utils/helpers.rs:37:23 3: bootstrap::Build::require_submodule at ./src/bootstrap/src/lib.rs:481:12 4: bootstrap::Build::require_and_update_all_submodules at ./src/bootstrap/src/lib.rs:502:13 By debugging i found that it fails to find src/gcc, which indeed is missing from the tarball.
Also using --disable-manage-submodules doesn't work since the config option is checked after the failing line:
Lines 481 to 482 in 4d91de4
