Include mcld/Config/Config.h in command line.

MCLinker upstream builds with -DHAVE_XXX in command line instead of
having a single config file (e.g., config.h) including in every file.
This commit adds "-include mcld/Config/Config.h" to the build commands
as if -DHAVE_XXX is supplied through the command line.
