this is a pure 32bit chroot, run with a 64bit kernel, using the linux32
personality to enter the chroot.  The build should not see any hint about the
64bit kernel.

The bootstrap JDK is OpenJDK 12 (32bit).  Most buildd infrastructure for any
Linux distribution doesn't mix 32/64 bit, including Fedora, Debian, Ubuntu.

yes, using the work-around, the build succeeds.
