stderr has captured the following...
-------------x-----------------x--------------x---
FAILED: load BTF from vmlinux: No such file or directory
make: *** [Makefile:1161: vmlinux] Error 255
make: *** Deleting file 'vmlinux'
------------x----------------x------------x--
5.16.2-rc1 builds for me.
Will the following link help...
