Debian, make and kernel rebuild troubles

Building the Linux kernel on my Debian/unstable machine recently caused some trouble: everytime I ran make, all files were (re-)compiled, not just the ones of modules I just added. The problem is related to the latest make version 3.81rc-1. Downgrading to 3.81beta4 solved this for me. It’s actually a bug in kbuild, but I can take months until the kernel includes a fix.
