Andrii Nakryiko	e4f7ac90c2	selftests/bpf: Mix legacy (maps) and modern (vars) BPF in one test ... Add selftest that combines two BPF programs within single BPF object file such that one of the programs is using global variables, but can be skipped at runtime on old kernels that don't support global data. Another BPF program is written with the goal to be runnable on very old kernels and only relies on explicitly accessed BPF maps. Such test, run against old kernels (e.g., libbpf CI will run it against 4.9 kernel that doesn't support global data), allows to test the approach and ensure that libbpf doesn't make unnecessary assumption about necessary kernel features.
