Migrate `libs-through-symlink` to rmake.rs Part of https://github.com/rust-lang/rust/issues/121876. This PR migrates `tests/run-make/libs-through-symlink/` to use rmake.rs. - Regression test for #13890. - Original fix PR is #13903. - Document test intent, backlink to #13890 and fix PR #13903. - Fix the test logic: the `Makefile` version seems to not actually be exercising the "library search traverses symlink" logic, because the actual symlinked-to-library is present under the `$(TMPDIR)` directory tree when `bar.rs` is compiled, because the `$(RUSTC)` invocation has an implicit `-L $(TMPDIR)`. The symlink itself was actually broken, i.e. it should've been `ln -nsf $(TMPDIR)/outdir/$(NAME) $(TMPDIR)` but it used `ln -nsf outdir/$(NAME) $(TMPDIR)`. The rmake.rs version now explicitly separates the two directory trees and sets the CWD of the `bar.rs` rustc invocation so that the actual library is *not* present under its CWD tree. I.e. it is now ``` $test_output/ # rustc foo.rs -o actual_lib_dir/libfoo.rlib actual_lib_dir/ libfoo.rlib symlink_lib_dir/ # CWD set; rustc -L . bar.rs libfoo.rlib --> $test_output/actual_lib_dir/libfoo.rlib ``` Partially supersedes #129011.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
