+Subject: [PATCH] librustc_llvm/build: Force link against libffi
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+`llvm-config --libs` doesn't output libffi in many cases.  Fixing it
+turned out to take quite a bit of effort, so force libffi linking in
+here for now.
