Dear maintainers,

libnsl 2.0 dropped support for NIS+, which causes sendmail FTBFS:

The problem is that the removal of the NIS+ support changes the
package description in the debian/control file. The following patch
fixes the issue:

Is that really enough?
IIRC this is just a description and the compile-time options needs to be
modified to remove NIS+ support from the package.

Yes, this is enough because NISPLUS support is autodetected (and that's
why the description in debian/control didn't match anymore).

Now if you prefer, it's also possible to disable the feature instead of
leaving it autodetected. That's what the following patch does:
