I'm reopening this bug because packages in stable *must* build in stable.

While it's true that this bug has not happened in the buildds so far,
I have been able to reproduce it every time during the last months/years:

https://jenkins-1.reliable-builds.org/job/gcc-8-cross/

and the end user is *not* to blame for this, as it is a Makefile bug.

(This is arguably a GPL violation, as the GPL mandates that packages
must include a working Makefile, which is not the case here).

If you need a machine on which this happens all the time, please contact
me privately and I will gladly provide a virtual machine for that.

Thanks.
