+# ld64 can now only be compiled using llvm and libc++ since it massivley uses
+# C++11 language fatures. *But additionally* the as driver now defaults to
+# calling clang as the assembler on many platforms. This can be disabled using
+# -Wa,-Q but since it's default we make llvm a static runtime dependency.
+
+# Also, llvm lto and disassembler interfaces are now widely used in cctools.
+# Since we cannot compile with gcc any more and every llvm since 3.4 has
+# provided those interfaces, we no longer support disabling them. That
+# indirectly makes xar a static runtime dependency.
