Linux library is not portable across distributions

[jpboivin]

Hello,

It seems that the current NuGet package does not work with the official .NET images (i.e. mcr.microsoft.com/dotnet/runtime:5.0) as liblua54.so is compiled against a specific version of glibc, which is not the one from this Docker image. This result in a typical DllNotFoundException as the system loader fails to load Lua's native dependencies.

I manually recompiled Lua from within the same Docker image to have a SO targeting the same version of the system libraries (and it worked), but this is less than ideal. I wonder if the Linux library shouldn't be compiled in a way that it will be portable across most Linux distributions using a somewhat recent version of glibc? In the past, I've used Holy Build Box for that, and it worked quite nicely.

Yes, deploying binaries on linux have been always painful. If you know a better and portable way please feel free to send a PR.

I know some libraries build using musl and depending only on system calls. I am not sure if this is the best approach
