+Subject: [PATCH 3/9] 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.
