* Fix compilation for output library - link to targets for ATT (amd-comgr, dw, elf) * Relax correlation ID retirement log failures - only fail for correlation ID retirement underflow when building in CI mode * Fix shebang for several files - license was inserted before shebang in several places * Update code coverage exclude folders for samples * Tweak to agent tests - test to make sure hsa agent is not the old value instead of testing that it is the new value * Fix libdw include/link --------- Co-authored-by: Jonathan R.
