llvm dev - Dec 2011 - [LLVMdev] [PATCH] llvm-config: Use "all" components by default.

Otherwise you will receive an empty output for
llvm-config --libs
llvm-config --libnames
llvm-config --libfiles

Additionally it fulfills following statement:

Typical components:
  all               All LLVM libraries (default).
