[Pkg-haskell-maintainers] Bug#756327: extra library build-dependencies left uppercase

[Max Kirillov]

Package: cabal-debian
Version: 3.9-1
Tags: patch

Hi.

This is a re-submit of the https://bugs.debian.org/658595 ,
which has been closed as "functionality your report is about
was dropped from the package". In fact it was not just
dropped, it was moved here, to cabal-debian.

Currently I am not doing things this would require
and cannot recheck it, but according to the sources the
defect is still there.

Proposed patch (I have not tested it! Only ported from the
original bug according to changes in code) follows:
