System.BadImageFormatException: Method has no body on CentOS

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

首先检查 LibGit2Sharp.Core.Proxy.git_repository_open 以及堆栈跟踪中显示的 Repository 构造函数。使用 Mono 5.16.0.187 在 CentOS 7.5 上通过 LibGit2Sharp v0.25.3 重现该故障，并将 native 方法的行为与链接的测试项目进行比较。当能够成功创建 Repository 实例且不发生 BadImageFormatException 时，即表示完成。
