Subject: Fix: Tests: utils.sh: fix unbound variable
X-Git-Url: http://git.efficios.com/?p=lttng-tools.git;a=commitdiff_plain;h=65e663fa0c098f8f8ddd0f0f3d91dbd25d1daa4d

Fix: Tests: utils.sh: fix unbound variable

When loading `utils.sh`, we test the `LTTNG_TEST_TEARDOWN_TIMEOUT` and
define it to a default value if it's not defined already.

When running bash test scripts with the `-u` option to error out when
encountering unset variables it prints an error and exit

This commit uses a trick found here:
