`dkms makedeb` fails on latest Debian (+ explanation)

[CRImier]

Currently, Debian Stretch (=> Ubuntu and Raspbian) has broken dkms. So, when you'll try to run dkms makedeb, it will fail like this:

DKMS: mkdeb completed.
Moving built files to /var/lib/dkms/esp8089/1.9.20181227/deb...mv: cannot stat '/tmp/dkms.lal1zd/esp8089-dkms_1.9.20181227_armhf.deb': No such file or directory
(bad exit status: 1)
Cleaning up temporary files...
cp /var/lib/dkms/esp8089/1.9.20181227/deb/*.deb .
cp: cannot stat '/var/lib/dkms/esp8089/1.9.20181227/deb/*.deb': No such file or directory
Makefile:114: recipe for target 'dkmsdeb' failed
make: *** [dkmsdeb] Error 1

The solution, for now, is to patch /usr/sbin/dkms like this:

--- /usr/sbin/dkms      2018-12-27 18:04:49.045945342 +0200

        export KVER="$kernelver"

Basically, replace the ${debian_build_arch} by all. Attaching the .patch file in a .zip (because GitHub). EDIT: oh wait, I confused the diff argument order, attaching a new patch and fixing the order: dkms_fix.zip

Thanks! I'll review this as soon as I can

No need to review, just a tip in case you can't compile the .deb, too - which seems likely.

Sorry, I looked at this before I groked what was going on. I have run into this before, and rediscover it every time I do a new release. Thanks for the reminder!

Note that I have a workaround at the bottom of the README using the upstream DKMS instead of Debian's.
