When building "tools/bpf" from the top of the Linux repository, the build system passes a value for the $(OUTPUT) Makefile variable to tools/bpf/Makefile and tools/bpf/bpftool/Makefile, which results in generating "libbpf/" (for bpftool) and "feature/" (bpf and bpftool) directories inside the tree. This commit adds such directories to the relevant .gitignore files, and edits the Makefiles to ensure they are removed on "make clean". The use of "rm" is also made consistent throughout those Makefiles (relies on the $(RM) variable, use "--" to prevent interpreting $(OUTPUT)/$(DESTDIR) as options. v2: - New patch.
