Please split this bit into separate patch and send it to bpf@vger targeting bpf-next. selftests/bpf are going through a lot of changes and I'd like to avoid any chance of conflicts.

OK, I'll split it.
Thank you,

Oops, this should be refined, since LDLIBS will not be passed when compiling. -pthread is complier option but -lpthread is linker option.
