...we disabled in swiftlang#81354 This requires a couple of supporting changes * under Linux, do not cross compile by default -- that will ensure that the compiler-rt build will use the just built compiler and not the system one (which may not be new enough for this purpose); * provide sanitizer flags depending on the linker the just built compiler will use -- this detection is brittle, so ensure the user can override those if needed.
