Hi, all

  I am trying to selfhost LLVM and Clang. Below is my flow,

Step 1. Build LLVM and Clang by using native gcc

$ ../llvm-2.9/configure --prefix=$INSTALL \

Step 2. Build LLVM and Clang by using clang built by step 1

$ CC=clang CXX=clang++ ../llvm-2.9/configure \
--prefix=$INSTALL --enable-optimized

  But in step 2, I have a compilation error below,

llvm[1]: Compiling Signals.cpp for Release build
In file included from /nfs_home/chenwj/test/llvm-2.9/lib/Support/Signals.cpp:30:
/nfs_home/chenwj/test/llvm-2.9/lib/Support/Unix/Signals.inc:31:10: fatal error: 'cxxabi.h' file not found
#include <cxxabi.h>

  Do I miss something like missing option or the Clang source needed to
be modified?
