1) Install qemu-system-arm.

2) Unpack kernel .deb, locate vmlinuz-4.9.0-8-armmp.
Or search your just-built zImage.

3) Run qemu (no root required):

qemu-system-arm -M virt -nographic -kernel vmlinuz-4.9.0-8-armmp

If you see a kernel panic - the outcome is positive, the kernel is OK.
If it just stays there eating 100% CPU - the outcome is negative.
