Zero fails to build on SPARC again, similar to JDK-8186578

[John Paul Adrian Glaubitz]

Hi!

Since building native JVM variant on linux-sparc is currently broken for
both OpenJDK-10 and OpenJDK-11, I tried building Zero instead. However,
Zero is broken as well:

This is reminiscent of JDK-8186578 and I would have expected the change made there
to be still working [2]. The relative path to memset_with_concurrent_readers_sparc.cpp
is still correct though.

Any suggestions?
