Build node.js with clang.

Since I chose clang as my favorite compiler,

The default compiler of node.js is g++, so it needs a little trick to force node.js to use clang. Here is it:

1. Run configure with clang support.

CC=clang ./configure --prefix=/usr

2. Specify complier.
Be sure you didn't install g++, then you can do so:

sudo ln -n /usr/bin/clang /usr/bin/g++
CC=clang make

3. Finally, make && make install.

(Don't forget to remove the fake g++ link).

make && sudo make install
sudo rm /usr/bin/g++

Good luck!
