[bpf-next,0/3] selftests: bpf: improve bpf object file rules

This set improves bpf object file related rules in selftests Makefile.
  - tell git to ignore the build dir "alu32".
  - extend sub-register mode compilation to all bpf object files to give
    LLVM compiler bpf back-end more exercise.
  - auto-generate bpf kernel object file list.

Jiong Wang (3):
  selftests: bpf: add "alu32" to .gitignore
  selftests: bpf: extend sub-register mode compilation to all bpf object
    files
  selftests: bpf: centre kernel bpf objects under new subdir
    "kern_progs"
