That's a fast reply! While trying to reproduce after sending out the mail, I
noticed this line:
$ (cd ~/Linux-src/linux/;git clean -xfd)
Removing arch/x86/include/generated/
warning: failed to remove arch/x86/include/generated/

Somehow that directory got root owned and I was unable to remove it without
using root power. After removing it, the build completes succesfully.

Sorry for the noise!

Thanks,
Peter
