+Subject: [PATCH] Export LLVM_DYLIB_COMPONENTS in LLVMConfig.cmake
+
+Summary:
+This is needed so that external projects (e.g. a standalone build of
+lldb) can link to the LLVM shared library via the USE_SHARED argument of
+llvm_config. Without this, llvm_config would add LLVM to the link list,
+but then also add the constituent static libraries, resulting in
+multiply defined symbols.
