[multilib] Add support to the autoconf build to substitute
a CLANG_LIBDIR_SUFFIX variable. This is necessary before I can add support for using that variable to CMake and the C++ code in Clang, and the autoconf build system does all substitutions in the LLVM tree. As mentioned before, I'm not planning to add actual multilib support to the autoconf build, just enough stubs for it to keep playing nicely with the CMake build once that one has support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224922 91177308-0d34-0410-b5e6-96231b3b80d8
