This is not the right place.

scripts/package/install-extmod-build is a script to set up
the build environment to build external modules.
It is shared by rpm-pkg, deb-pkg, and pacman-pkg.


https://github.com/torvalds/linux/blob/v6.12-rc5/scripts/package/install-extmod-build#L34

You will see how objtool is copied.




(Anyway, it depends on your urgency.
My hope is to support objtool and resolve_btfids in more generic ways.)
