rust/tests/run-make/invalid-symlink-search-path/rmake.rs

// In this test, the symlink created is invalid (valid relative to the root, but not relatively to
// where it is located), and used to cause an internal compiler error (ICE) when passed as a library
// search path. This was fixed in #26044, and this test checks that the invalid symlink is instead
// simply ignored.
//
// See https://github.com/rust-lang/rust/issues/26006

//Reason: symlink requires elevated permission in Windows
