#     kbuild: make clean rule robust against too long argument error
#     
#     Commit cd968b97c492 ("kbuild: make built-in.a rule robust against too
#     long argument error") made a build rule robust against "Argument list
#     too long" error.
#     
#     Eugeniu Rosca reported the same error occurred when cleaning an external
#     module.
#     
#     The $(obj)/ prefix can be a very long path for external modules.
#     
#     Apply a similar solution to 'make clean'.
