-Subject: [PATCH 2/3] mk: for stage0, use RUSTFLAGS to override target libs dir
-
-Setting HLIB specially for stage0 (and even more specially for windows)
-also affects the location we place TLIB. To keep the TLIBs we build in
-the place requested by configure, use '-L' and '--sysroot' to point
-stage0-rustc at the appropriate location.
