[Pkg-dns-devel] Bug#845941: unbound FTCBFS: uninstallable python Build-Depends, configures for the build architecture

[Helmut Grohne]

Source: unbound
Version: 1.5.10-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

unbound fails to cross build from source for a number of reasons. First
of all, its python Build-Depends are not installable as Python cannot be
installed for foreign architectures (its postinst fails). What is needed
here is not a host architecture Python, but a build architecture Python
and host architecture Python development files.

Secondly, it configures for the build architecture, because none of the
explicit ./configure invocations carry the necessary --host flag.
Indirecting them through dh_auto_configure fixes that as debhelper knows
when to pass --host.

And the final problem is #840080 and not fixable in unbound. I expect it
to be fixed in a week.

Can you apply the attached patch?
