<pre>I have firstly compiled clang for host builds and now using the clang for the
host builds I am using the clang for target build using the following command
cmake ../llvm/ -DCMAKE_CROSSCOMPILING=True
-DCMAKE_INSTALL_PREFIX=/home/adal/clang_3.2_cross_arm/
-DLLVM_TABLEGEN=../build_cmake/bin/llvm-tblgen
-DCLANG_TABLEGEN=../build_cmake/bin/clang-tblgen
-DLLVM_DEFAULT_TARGET_TRIPLE=arm-none-eabi -DLLVM_TARGET_ARCH=ARM
-DLLVM_TARGETS_TO_BUILD=ARM -DCMAKE_CXX_FLAGS='-target armv7r-none-eabi -I

../build_cmake/lib/' -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++
However the build beaks giving output ...
