Comment 53 for bug 1710278

Ok I made some progress

bind9-single-thread is now "threads support is disabled" according to "named -V"

and

bind9 is still "threads support is enabled" still according to "named -V"

There is a few things to fix still here and there due to the recent change, but at least I think I found what dh_install needed to separate the binaries into their respective binary package.

It is a bit more difficult since it involves multiple recompilation of the same software but with different configuration options for each of them. Still need some time to refine the configuration and test again.
