[Debian-med-packaging] Bug#922149: t-coffee ignores build failures

[Helmut Grohne]

Source: t-coffee
Version: 12.00.7fb08c2-2
Severity: serious
Justification: policy 4.6

t-coffee's debian/rules passes -i through dh_auto_build to make. That's
the equivalent to ignoring all return codes of compiler invocations and
thus violating the spirit of policy section 4.6. I argue that -i
violates common sense. Its presence makes debugging build failures next
to impossible. Please drop the -i flag.
