+# b/17574078: Need to disable coverage until we have a prebuilt libprofile_rt.
+# Since this is a static library built with clang, it needs to link
+# libprofile_rt when it is linked into the final binary. Since the final binary
+# is built with GCC, it won't link libprofile_rt. We can't very easily just add
+# libprofile_rt to all link lines the way we've done for libgcov because
+# libprofile_rt isn't prebuilt, and it would be tricky to write a rule that
+# would make sure libprofile_rt is built.
