[PATCH 6.11 261/695] selftests/bpf: Fix wrong binary in Makefile log output

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Ambardar <tony.ambardar@xxxxxxxxx>

[ Upstream commit 3ece93a4087b2db7b99ebb2412bd60cf26bbbb51 ]

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
  ...
  CLNG-BPF [test_maps] access_map_in_map.bpf.o
  GEN-SKEL [test_progs-no_alu32] access_map_in_map.skel.h
  ...
  CLNG-BPF [test_maps] access_map_in_map.bpf.o
  GEN-SKEL [test_progs-cpuv4] access_map_in_map.skel.h

After fix:
  CLNG-BPF [test_progs] access_map_in_map.bpf.o
  GEN-SKEL [test_progs] access_map_in_map.skel.h
  ...
  CLNG-BPF [test_progs-no_alu32] access_map_in_map.bpf.o
  GEN-SKEL [test_progs-no_alu32] access_map_in_map.skel.h
  ...
  CLNG-BPF [test_progs-cpuv4] access_map_in_map.bpf.o
  GEN-SKEL [test_progs-cpuv4] access_map_in_map.skel.h

Fixes: 89ad7420b25c ("selftests/bpf: Drop the need for LLVM's llc")
