[Debian-med-packaging] Bug#922196: t-coffee FTCBFS: confuses C/C++ compilers

Hi Andreas,

thank you for quickly removing the -i flag. Now diagnosing why t-coffee
fails to cross build became a lot easier. As it happens, the upstream
Makefile stores g++ in CC, but for cross compilation dh_auto_build
overrides that with a C cross compiler. That doesn't work well. All we
need to do here is store the C++ compiler in CC. Please consider
applying the attached patch (possibly after buster).

Helmut
