Hi,

Thanks for the testing and the report, Matthias!

This whole shebang is Zero-specific problem, so I see no reason to link libatomic unconditionally.

AFAICS, Matthias' patch adds libatomic to platforms that are nominally supported by Server (i.e. 
ARM). It used to handle only MIPS that is only supported by Zero. So the patch would be a bit 
reworked to accept only Zero.

I did it here:
   https://bugs.openjdk.java.net/browse/JDK-8259043
   https://github.com/openjdk/jdk16/pull/76

Matthias, please give it a spin, if you can.
