tests/run-make/allocator-shim-circular-deps/rmake.rs

// This test is designed to intentionally introduce a circular dependency scenario to check
// that a specific compiler bug doesn't make a resurgence.
// The bug in question arose when at least one crate
// required a global allocator, and that crate was placed after
// the one defining it in the linker order.
// The generated symbols.o should not result in any linker errors.
// See https://github.com/rust-lang/rust/issues/112715
