Added a few clarifying steps the the "building clang" section.

+<p>Note that the C front-end uses LLVM, but does not depend on\r
+  llvm-gcc.  If you encounter problems with building clang, make\r
+  sure you have the latest SVN version of LLVM.  LLVM contains\r
+  support libraries for clang that will be updated as well as\r

 <p>We will eventually integrate this better as a sub-project, but for now it builds a single tool named 'clang'.<br>\r
 Once llvm is built in this way, you can compile C code.\r
