	Adapt Makefile to support BPF skeleton generation beyond single profiler.bpf.c case. Also add vmlinux.h generation and switch profiler.bpf.c to use it. clang-bpf-global-var feature is extended and renamed to clang-bpf-co-re to check for support of preserve_access_index attribute, which, together with BTF for global variables, is the minimum requirement for modern BPF programs.

2020-03-13	bpftool: Only build bpftool-prog-profile if supported by clang	Song Liu	1	-0/+4
	bpftool-prog-profile requires clang to generate BTF for global variables. When compared with older clang, skip this command. This is achieved by adding a new feature, clang-bpf-global-var, to tools/build/feature.
