coreboot classes: Add dynamic classes to coreboot

Provide functionality to create dynamic classes based on program name and the
    architecture for which the program needs to be compiled/linked. define_class
    takes program_name and arch as its arguments and adds the program_name to
    classes-y to create dynamic class and compiler toolset is created for the
    specified arch. All the files for this program can then be added to
    program_name-y += .. Ensure that define_class is called before any files are
    added to the class. Check subdirs-y for order of directory inclusion.

One such example of dynamic class is rmodules. Multiple rmodules can be used
    which need to be compiled for different architectures. With dynamic classes,
    this is possible.
