"""
This test produces two shared libraries:

1. libt-instr.so is instrumented
2. libt-no-instr.so is built with profile rt linked in (via -u<hook>), but the object file is built
   with instrumentation turned off.

The test verifies concatenating profiles with only headers and no profile data and counters.
