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.

Even in quiet mode, make finishes with
rm tools/bpf/bpf_exp.lex.c
That's because it considers the file to be intermediate. Silence that by
mentioning the lex.c file instead of the lex.o file; the dependency still
stays.

Currently, make bpf_install in tools/ does not respect DESTDIR. Moreover, it
installs to /usr/bin/ unconditionally.
Let it respect DESTDIR and allow prefix to be specified. Also, to be more
consistent with bpftool and with the usual customs, default the prefix to
/usr/local instead of /usr.

Currently, the programs under tools/bpf (with the notable exception of
bpftool) do not respect the output directory (make O=dir). Fix that.

Bpftool build is broken with binutils version 2.29 and later.
The cause is commit 003ca0fd2286 ("Refactor disassembler selection")
in the binutils repo, which changed the disassembler() function
signature.
Fix this by adding a new "feature" to the tools/build/features
infrastructure and make it responsible for decision which
disassembler() function signature to use.

We currently only have BPF tools in the tools/net directory.
We are about to add more BPF tools there, not necessarily
networking related, rename the directory and related Makefile
targets to bpf.
