So in the end it looks like we will only support checking both .jnilib and .dylib on Mac:

1. When using System.loadLibrary()
2. The class calling System.loadLibrary() was NOT loaded from a custom class loader
3. isAbsolute is false, which implies System.load() was called.

I saw the macosx discussion, and I think this is fine. If you're calling System.load() you know what file you want to load, and the extension shouldn't be inferred. Likewise, we shouldn't override the policy of a non-system class loader.

I enthusiastically approve this change. :-)
