It is quite certain that the problem was introduced with the equivs 2.3.0
release. If you run the "debbisect" script from this merge request
https://salsa.debian.org/debian/devscripts/-/merge_requests/177#note_148500
then you will get:

    $ ./scripts/debbisect --depends=equivs --cache=./cache 2020-04-18 2020-04-20 'chroot "$1" equivs-build /usr/share/doc/equivs/examples/webserver.ctl'
    [...]
    bisection finished successfully
      last good timestamp: 2020-04-19 06:52:31.476563+02:00
      first bad timestamp: 2020-04-19 10:35:09.156250+02:00
    only one package differs: equivs is the culprit

Notice that the test-command executes equivs-build with one of the provided
examples (webserver.ctl), so the problem is not mk-build-deps specific.

I wrote an autopkgtest which also demonstrates the problem:

https://salsa.debian.org/perl-team/modules/packages/equivs/-/merge_requests/5

Since all examples fail with the message "Unmet build dependencies:
build-essential:native" I'm raising the severity to grave. I'm not able to find
a way to craft a control file that is still working with equivs.

Thanks!

cheers, josch
