Added boilerplate for aarch64 and ppc64le by judovana · Pull Request #7 · lmdbjava/native

Hello!

This PR is adding "support" for aarch64 and ppc64le linux platforms.
It currently do not use cross compilation, and thus is relying only on self build jars in ~/.m2 .
The approach is not ideal, as true in consuming lmdbjava project is not exactly working and thus the future release will enforce upload of binaries compiled on ppc64le/aarch64 , which I'm happy to provide.
The tests of lmdb are passing on those arches, but I have not verified manually.
Before approving/rejecting this PR, please see PR on this topic into lmdb java, which I have ready locally, and will publish any moment.

Looking forward for ideas.
