+Subject: [PATCH] Apply the same fallbacks as runtimes search for stdlib search
+
+When building clang with e.g. LLVM_ENABLE_RUNTIMES=libcxx;libunwind,
+those runtimes end up in the stdlib search directory, and when
+LLVM_ENABLE_PER_TARGET_RUNTIME_DIR is set, that ends up in a
+target-specific subdirectory. The stdlib search does handle the
+situation, but when the target in question is Android, the same issues
+as those that required fallbacks for runtimes search apply.
+
+Traditionally, those libraries are shipped as part of the Android NDK,
+but when one builds their own clang for Android, they may want to use
+the runtimes from the same version rather than the ones from the NDK.
