Makefile: Make full use of src-to-obj macro

There were several spots in the tree where the path to a per class
    object file was hardcoded. To make use of the src-to-obj macro for
    this, it had to be moved before the inclusion of subdirs. Which is
    fine, as it doesn't have dependencies beside $(obj).

Tested by verifying that the resulting coreboot.rom files didn't change
    for all of Jenkins' abuild configurations.
