Is this still necessary if we're using the JNA version?

I don't think this is strictly required with JNA imho.

Doesn't the NativeLibrary instance need to be disposed somewhere?

Why not also leveraging java.library.path system prop ?

What's Changed
Set the Lazy and Global flags when loading the Gandiva library for JNI so that system functions are visible to the compiled LLVM code.
See also apache/arrow#41497 for much past discussion on this same fix.
Closes #657 and apache/arrow#40839.
