I have looked a little more into the test support code. It appears that
at least some test scripts hardcode the path to the lttng binaries
relative to the test directory. Removing those path prefixes indeed
resolved the test failures in the cases I was looking into. Of course,
that would break the `make check` target as for in-development testing
the binaries would no longer be found. Is there any reason a simple
adjustment of the PATH variable would not be enough ?
