build.log of failed emerge

After updating portage to version 2.2.1, virtualbox-modules fails to (re-)emerge. Looks like portage is messing up some permissions:

Makefile:1418: .vmlinux.cmd: Permission denied

  ERROR: Kernel configuration is invalid.
         include/generated/autoconf.h or include/config/auto.conf are missing.
         Run 'make oldconfig && make prepare' on kernel src to fix it.

make[3]: stat: include/config/auto.conf: Permission denied

The complete build.log is attached. Reproducible on different machines. Before portage update virtualbox-modules emerges fine.

With FEATURES=userpriv, the ebuild runs as "portage" user and "portage" group. So, you may need to adjust ownership of files in some cases. Alternatively, you can remove userpriv from FEATURES:

  echo 'FEATURES="${FEATURES} -userpriv -usersandbox"' >> /etc/portage/make.conf
