Changed to:

tools: Change FEATURE_TESTS and FEATURE_DISPLAY to weak binding

The style is copied from lib traceevent. I'll change it as your suggestion.

[..]

Thanks a lot. I changed titles again:

tools lib traceevent: Install libtraceevent.a into libdir
tools: Change FEATURE_TESTS and FEATURE_DISPLAY to weak binding
tools: Add __aligned_u64 to types.h
bpf tools: Introduce 'bpf' library to tools
bpf tools: Allow caller to set printing function
bpf tools: Define basic interface
bpf tools: Open eBPF object file and do basic validation
bpf tools: Check endianess and set swap flag according to EHDR
bpf tools: Iterate over ELF sections to collect information
bpf tools: Collect version and license from ELF sections
bpf tools: Collect map definitions from 'maps' section
bpf tools: Collect config string from 'config' section
bpf tools: Collect symbol table from SHT_SYMTAB section
bpf tools: Collect eBPF programs from their own sections
bpf tools: Collect relocation sections from SHT_REL sections
bpf tools: Record map accessing instructions for each program
bpf tools: Clear libelf and ELF parsing resrouce to finish opening
bpf tools: Add bpf.c/h for common bpf operations
bpf tools: Create eBPF maps defined in an object file
bpf tools: Relocate eBPF programs
bpf tools: Introduce bpf_load_program() to bpf.c
bpf tools: Load eBPF programs in object files into kernel
bpf tools: Introduce accessors for struct bpf_program
bpf tools: Introduce accessors for struct bpf_object
perf tools: Add new 'perf bpf' command
perf tools: Make perf depend on libbpf
perf bpf: Add 'perf bpf record' subcommand
perf bpf: Add bpf-loader and open ELF object files
perf bpf: Collect all eBPF programs
perf bpf: Parse probe points of eBPF programs during preparation
perf bpf: Probe at kprobe points
perf bpf: Load all eBPF object into kernel
perf tools: Add a bpf_wrapper global flag
perf tools: Add bpf_fd field to evsel and introduce new event syntax
perf bpf: Generate event argv for other commands
perf bpf: Pass generated arguments to cmd_record()

Do you have further suggestion?

Thank you.
