Dear Maintainer,

As per an upstream bug report [1], big-endian ppc64 (ABIv1) is no longer supported for OpenJDK 23+.

   * What led up to the situation?

Attempted to sbuild the 'jpeg-xl' and 'opencv' Debian packages on an Apple G5 that required Java.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Observed 'Illegal instruction' errors in the logs when the configury was attempting to determine the Java version.

   * What was the outcome of this action?

Package failed to build unless the 'nojava' Build-Profile was specified.
