I wonder whether it's not a problem in the upstream commits playing weird
games with the makefile variables. For example, this sentence in upstream
commit 13e07691a16f ("tools/resolve_btfids: Alter how HOSTCC is forced"):
"[...] just pass CC as HOSTCC to Makefile.build [...]" does not raise much
confidence.
