coreboot classes: Add dynamic classes to coreboot
Provide functionality to create dynamic classes based on program name and 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. Also, 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.
