[Debian-astro-maintainers] Bug#915163: montage does not trap errors from make

[Helmut Grohne]

Source: montage
Version: 6.0+dfsg-1
Severity: serious
Tags: upstream
Justfication: policy 4.6

montage's lib/src/Makefile chains make invocations with ";". Doing so is
prohibited by the Debian policy section 4.6, because it makes diagnosing
build failures unnecessarily hard and it can result in misbuilds going
unnoticed. Please chain the commands with "&&" or add "set -e".
