"""
This test produces three shared libraries:
1. libt-instr.so is instrumented
2. libt-no-instr1.so is not instrumented
3. libt-no-instr2.so is built with profile rt linked in (via -u<hook>), but the object file is built
with instrumentation turned off.
After the libraries are built, the main program is then built with/without instrumentation and linked
against 3 libraries above.
The test is to verify that programs linked against these shared objects with and without instrumentation
enabled behave as expected.
