Bug#1057390: openjdk-21: Please add patch to support SPARCV9

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Source: openjdk-21
Version: 21.0.1+12-2
Severity: normal
Tags: patch
User: debian-sparc@lists.debian.org

Hello!

The attached patch adds SPARCV9 support to OpenJDK. It has been successfully
tested against OpenJDK 21 on stadler.debian.net. I will use this patch now
to build openjdk-21 and upload to unreleased.

Thanks,
Adrian
