Leif,

unfortunately, I have no access to a A64 machine.
But I found on Google, that you may have to add the '-m64' option to the link lines to force the compiler and linker to produce 64-bit binaries.
If it still fails, I would enable the debug output of gcc to see, which other libraries it is trying to link into the JNI library.
Perhaps one of them is not a 64-bit one. And they all should be shared libraries, not static ones.

Cheers,
Andreas
