rustbuild: Build tests with LLD if `use-lld = true` was passed Addresses https://github.com/rust-lang/rust/pull/76127#discussion_r479932392. Our test suite is generally ready to run with an explicitly specified linker (https://github.com/rust-lang/rust/pull/45191), so LLD specified with `use-lld = true` works as well. Only 4 tests fail (on `x86_64-pc-windows-msvc`): ``` ui/panic-runtime/lto-unwind.rs run-make-fulldeps/debug-assertions run-make-fulldeps/foreign-exceptions run-make-fulldeps/test-harness ``` All of them are legitimate issues with LLD (or at least with combination Rust+LLD) and manifest in segfaults on access to TLS (https://github.com/rust-lang/rust/pull/76127#issuecomment-683473325). UPD: These issues are caused by https://github.com/rust-lang/rust/issues/72145 and appear because I had `-Ctarget-cpu=native` set. UPD: Further commits build tests with LLD for non-MSVC targets and propagate LLD to more places when `use-lld` is enabled.
