Description
Reproduction steps
I use CAKE to automate build process. I run my build script on CentOS and it throws an exception
To reproduce the issue, try to create an instance of the 'Repository' class.
I've created a test project reproducing similar error, but on MacOS.
I also use CAKE script, but the original one is more complex than the test one, but in any way the library also throws similar exception related to native methods.
...
var repo = new Repository("./.git");
...
Actual behavior
Error: System.AggregateException: One or more errors occurred. ---> System.BadImageFormatException: Method has no body

Expected behavior
The constructor returns an instance of the Repository

Research direction
Start by inspecting LibGit2Sharp.Core.Proxy.git_repository_open and the Repository constructor shown in the stack trace. Reproduce the failure with LibGit2Sharp v0.25.3 on CentOS 7.5 using Mono 5.16.0.187 and compare the native-method behavior with the linked test project. Done means creating a Repository instance succeeds without BadImageFormatException.
