LLVM configured and successfully built as :
/configure --with-llvmgccdir=/llvm-gcc-4.2 --enable-optimized --enable-jit --prefix=<llvm-install/llvm --target=arm-unknown-linux-gnueabi
llvm-gcc-4.2 configured as :
<llvm-gcc-4.2-source>/configure --prefix=<llvm-install/llvm-gcc-4.2 --program-prefix=llvm-x86_64-arm --enable-llvm=/llvm --disable-multilib --target=arm-none-linux-gnueabi --with-sysroot= --enable-languages=c,c++
