Bug#890979: lintian gir-missing-typelib-dependency is not case insensitive

[Laurent Bigonville <bigon@debian.org>]

Package: lintian
Version: 2.5.75
Severity: normal

Hi,

lintian wrongly emits gir-missing-typelib-dependency warning.

For example, libfarstream-0.2-dev depends against gir1.2-farstream-0.2,
but lintian still complains.

$ apt-file show libfarstream-0.2-dev|grep gir
libfarstream-0.2-dev: /usr/share/gir-1.0/Farstream-0.2.gir
$ apt-file show gir1.2-farstream-0.2|grep typelib
gir1.2-farstream-0.2: /usr/lib/x86_64-linux-gnu/girepository-1.0/Farstream-0.2.typelib
$ apt-cache show libfarstream-0.2-dev|grep gir
Depends: gir1.2-farstream-0.2, libfarstream-0.2-5 (= 0.2.8-4), libgstreamer1.0-dev
