Oscar Fuentes 51a072b7d8 Changes for building Clang and others using LLVM as an external
library.

Installs tblgen (required by Clang).

Translates handling of user settings and platform-dependant options to
its own file, where it can included by another project.

Installs the .cmake files required by projects like Clang.
