#     kbuild: make *.mod not depend on *.o
#     
#     The dependency
#     
#         $(obj)/%.mod: $(obj)/%$(mod-prelink-ext).o
#     
#     ... exists because *.mod files previously contained undefined symbols,
#     which are computed from *.o files when CONFIG_TRIM_UNUSED_KSYMS=y.
#     
#     Now that the undefined symbols are put into separate *.usyms files,
#     there is no reason to make *.mod depend on *.o files.
