Support Older version of Linux distribution

[sitalkedia]

We are currently adding zstd compression support to Spark and we are using ztsd-jni for that. We are facing Spark unit tests failure because the library is compiled with a newer glibc requirement than the amplab machines have. Can you tweak your compilation to support older Linux distros?

See apache/spark#18805 (comment) for more details.

Thanks for notification. I just pushed v1.3.2-2 to maven that has the linux-amd64 library compiled on older distro (debian 6). It should become public in several hours. Please let me know if it works as expected on your test fleet.

Thanks a lot for the quick turn around on this. Will let you know how it goes.

This may also fix #43 (not sure what glibc that distro has).

@vanzin , I doubt - they are using musl libc in apline linux by default. I still have not found a way to switch the .so based on the libc type/version. I will make some experiments to see if an alpine linux binary can work with glibc based distros.

BTW, the change worked and Spark unit tests passed now.

@sitalkedia, great! Thanks for coming back with the results. I will update my release process to use older distro for the amd64 shared object compilation.
