Source files modified: * Makefile.config - Checks whether libbpf is installed on the system. If so, we add -lbpf to LIBS_FEATURES, -DCONFIG_HAS_LIBBPF to FEATURE_DEFINES and set CONFIG_HAS_LIBBPF. This allows us to check for the presence of libbpf before compiling or executing BPF c/r code and ZDTM tests. * Makefile - Set CONFIG_HAS_LIBBPF to clean all files.
