[vlc-devel] [PATCH 2/2] test: add make_check_wrapper.sh

[Thomas Guillem]

This helper will print on the standard input the failing test-suite.log and
core dump in case of a failing make check.

This script should be used by build bots in order to find the root cause of
failing tests.

See https://jenkins.videolan.org/job/vlc-continuous/job/vlc-cont-debian-x86_64/5852/console
---

Changes since last patch:
 - use $() instead of ``
 - use sed instead of grep|cut|tail|awk
 - fix one hardcored test-suite.log value
