Make log output incorrectly shows 'test_maps' as the binary name for every 'CLNG-BPF' build step, apparently picking up the last value defined for the $(TRUNNER_BINARY) variable. Update the 'CLANG_BPF_BUILD_RULE' variants to fix this confusing output. Current output: CLNG-BPF [test_maps] access_map_in_map.bpf.o GEN-SKEL [test_progs] access_map_in_map.skel.h ...
