[lttng-dev] [RFC/PATCH 1/3] babeltrace: use AM_TESTS_ENVIRONMENT for tests

[nathan_lynch@mentor.com (Nathan Lynch)]

Export convenient variables from the build system into the runtime
environment of the testcases, so that fewer test scripts need to be
generated at configure time using Autoconf variable substitutions.

This makes it less tedious to add and work on testcases in script
form.

The user can supplement or override settings in AM_TESTS_ENVIRONMENT
by using TESTS_ENVIRONMENT on the command line.
