+# XXX: See the log for r232932 as to why the above -mlongcall is needed.  Since
+# clang doesn't support -mlongcall, and testing shows a clang linked with a
+# clang-built csu segfaults, this must currently be compiled with gcc.  Once
+# clang supports -mlongcall, or we get a fixed ld, this can be revisited.
