In /lib/modules/4.4.0-kali1-686, I don't have "build" or "source" directories.

Code:
# uname -r
4.4.0-kali1-686
# apt-get install linux-headers-4.4.0-kali1-686
...
Note, selecting 'linux-headers-4.4.0-kali1-686-pae' for regex 'linux-headers-4.4.0-kali1-686'
-linux-headers-4.4.0-kali1-686-pae is already the newest version (4.4.2-3kali1)
According to uname -r, I'm not using the PAE kernel, but apt-get insists on grabbing PAE header files.

I can't install without these headers. How do I proceed?
