The previous patch builds tools/bootconfig during 'make prepare' to render the embedded bootconfig cmdline, but nothing removes it on 'make clean', leaving the compiled tool and its objects behind. Wire a bootconfig_clean hook into the top-level clean target so the compiled tool and its objects are removed by make clean, matching the prepare-wired tools/objtool and tools/bpf/resolve_btfids. The hook runs tools/bootconfig's Makefile via $(MAKE), which the kernel build invokes with -rR (MAKEFLAGS += -rR). -rR drops the built-in $(RM) variable, so the existing "$(RM) -f ..." clean recipe would expand to a bare "-f ..." and fail. Spell the recipe with a literal "rm -f" so it keeps working both standalone and when invoked from Kbuild.
