Compilation vboxhost fail #207

Hello,

Since I upgraded the kernel, I can't compile the module vboxhost:
$ yaourt -S linux-samus4
$ yaourt -S linux-samus4-headers

(I tried to install directly binary from the repo, same result)

$ sudo dksm build vboxhost/5.2.6_OSE -k 4.15.0-6-ph
$ cat /var/lib/dkms/vboxhost/5.2.6_OSE/build/make.log

DKMS make.log for vboxhost-5.2.6_OSE for kernel 4.15.0-6-ph (x86_64)
