Comment # 4 on bug 1230414 from Takashi Iwai

Thanks for confirmation.

It seems that -j option was passed since some time ago (around kernel 5.18),
commit b4f72786429cc57383ff41e02407726313ca178d
    scripts/pahole-flags.sh: Parse DWARF and generate BTF with multithreading.

An easy way would be to patch in us downstream side, but it'd be better to
inform upstream about the problem in anyway.  Adding Shung-Hsi to Cc.
