I see you are getting the details right from the start. Awesome.

The Build-Depends of openldap are currently cross-unsatisfiable
regardless of whether you are in a bootstrap setting or not. The
technical reason is that you depend on the host architecture perl, but
essential depends on the build architecture perl and perl is not
coinstallable with itself. The non-technical explanation is that you
want to execute perl and thus should be depending on the build
architecture perl, which is generally available during a cross build. To
do that you mark it as "perl:native". The archive support for ":native"
is still not known to work in all places, so I skipped that part in my
patch. Since perl is "M-A:allowed" you can achieve the same effect by
saying "perl:any" and have it work today.

I note that you seem to be using "host's perl" with a (Mozilla'ish)
terminology that differs from the GNU terminology. I generally use the
terminology from "man dpkg-architecture" section "TERMS".

All other Build-Depends should be ready for crossing unless I am getting
things wrong again.

TL;DR: perl (not libperl-dev) is always available for cross builds even
in a bootstrap setting. It just needs to be written as "perl:any" (or
"perl:native" in a not so distant future).
