af27072 broke the build on Darwin.
There does not seem to be any way to sanely enable tests on Darwin.
Tests initially fail because of missing 'greadelf'
expected by test/run_readelf_tests.py.
This is fixed by:
- adding 'binutils-unwrapped' to checkInputs
- hardlinking 'readelf' to 'greadelf' in a temp bin dir
- exporting temp bin dir to PATH
This leads to further test failures because of 'readelf' version mismatch
causing output inconsistencies.
See test/run_readelf_tests.py:31 for further details.
