Subject: [PATCH] I should not have been born.

This patch is a ugly, but a this moment I have no better alternatives to
offer.

 - Add a script to compile the llvm sources through the standard
   makefiles instead of the bsd build system. The produced gold plugin
   is then copied into the source tree and used from there by the BSD
   Makefiles.
