This is a long-standing issue:

https://mail.openjdk.java.net/pipermail/distro-pkg-dev/2014-July/028503.html

but clearly tested by so few that no-one has ever been motivated to make
this change upstream! We've carried it downstream in IcedTea for over
half a decade, but I've never really run into it myself, as it's rare
that I'd build for x86-32, never mind x86-32+Zero.

I would suggest going the !defined(ZERO) code rather than building the
JDK-8023956 hack on Zero x86. I'm not sure how much sense it even makes
to have that code when there is no JIT.

Thanks,
