Install Errors

I kept hitting an errors when trying to install libaec. Finally I found some changes on the project website: https://gitlab.dkrz.de/k202009/libaec/commit/9bd2d0857cdc6375ad7570516f064eb264530378

I replaced the lines in libaec-0.3.3/tests/sampledata.sh with the ones noted in the OS X and clang fixes noted above.
