Bug#911451: Add Info/Pendantic tag if Build-Depends-Package is not present in .symbols file

[Laurent Bigonville <bigon@debian.org>]

Package: lintian
Version: 2.5.109
Severity: wishlist

Hi,

.symbols file can contain the Build-Depends-Package field which indicate
what is the -dev package for the library:

Build-Depends-Package
    It indicates the name of the “-dev” package associated to the
    library and is used by dpkg-shlibdeps to make sure that the
    dependency generated is at least as strict as the corresponding
    build dependency (since dpkg 1.14.13).

This is an intresting field as it allows packages to not hardcode this
information multiple time.

Shouldn't lintian generate a Info or Pendantic tag if this is missing?

Kind regards,

Laurent Bigonville
