make test: print a warning in case a core_pattern contains a filter program
The default config on Ubuntu 16.04.4 desktop results in truncated cores when running make test which coredumps. Uninstalling the filter program (apport) makes the corefiles normal size. Print a warning about that fact, so the others potentially affected didn't have to wonder. Change-Id: Iba4b0a2765a25100d6e24fd7f4de0e0339efd835 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
