[DRE-maint] Bug#893501: ruby2.5 FTCBFS: configures for the build architecture

So I wanted to apply this, but it appears that non-cross builds now
also need --with-baseruby, and that's not good - we don't want a
cyclic (build-)depedency.

Maybe you can have another look at the patch?

I realise the reply to this bug comes somewhat late.

Thanks,
