Mac OS X 32bit x86 build fails for jdk12u

[Philip Race]

I think you are right. I don't remember even JDK 7 having a 32 bit version.
There may have been some unused partial support to create one, but we
never shipped such a thing - nor were there internal 32 bit builds.

Also macOS 10.15 doesn't support 32 bit applications.
So when 10.14 goes EOSL in about 17 months from now, it'll be history.
