[Debian-med-packaging] Bug#932652: cd-hit FTCBFS: unconventional compiler variable

[Helmut Grohne]

Source: cd-hit
Version: 4.6.8-2
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

cd-hit fails to cross build from source, because the upstream Makefile
stores the C++ compiler in the variable CC while dh_auto_build passes a
C compiler there. Please consider applying the attached patch.
