Compile of Anbox fails because kernel function kallsyms_lookup_name() is unexported

I took your advice, enabled the anbox flags, and recompiled the arch linux kernel, and it looked like it got pretty far along, until it aborted with the following error message about the (mis)location of objtool.  Here is the last couple of lines emitted from makepkg:

INSTALL sound/usb/snd-usb-audio.ko
  INSTALL sound/usb/snd-usbmidi-lib.ko
  INSTALL sound/xen/snd_xen_front.ko
  INSTALL virt/lib/irqbypass.ko
  DEPMOD  5.7.6-arch1-1-anbox

install: cannot stat 'tools/objtool/objtool': No such file or directory
==> ERROR: A failure occurred in package_linux-anbox-headers().

The line that fails in PKGBUILD seems to be 108:

# add objtool for external module building and enabled VALIDATION_STACK option
108  install -Dt "$builddir/tools/objtool" tools/objtool/objtool

It feels like I am so close ...

Have you tried looking yet to see if you can find objtool on your system and correcting the PKGBUILD? Likely you just need to make a pull of the kernel repo and try your changes again.
