8331730: [8u] GHA: update sysroot for cross builds to Debian bullseye

[zzambers]

Updates GHA to use Debian bullseye for cross build sysroot. Motivation for this are broken builds on s390x and ppc64le in recent test runs. This is due to disappearance of s390x and ppc64le arches in repos of buster (currently used Debian). Not sure why arches disappeared, but turns out that buster soon reaches end of LTS support (2024-06-30).

As Debian bullseye (next version) again has all aches in its repos, update solves both issues. In newer JDKs, sysroot update to bullseye was included in JDK-8293107 (GHA: Bump to Ubuntu 22.04). I have tried Ubuntu update in GHA as well, but it failed to build on some platforms (aarch64, ppc64le) with errors such as:

/home/runner/work/jdk8u-dev/jdk8u-dev/jdk/hotspot/src/share/vm/adlc/arena.cpp:82:19: error: ISO C++17 does not allow ‘register’ storage class specifier [-Werror=register]
   82 |   register Chunk *k = _first;
      |                   ^

Seems to be JDK-8281096 (Flags introduced by configure script are not passed to ADLC build). So Ubuntu update is blocked by that (and there seem to be some complications there). That's why I would like to do this separately from Ubuntu upgrade.

Testing in GHA: OK
(This only affects cross-builds in Linux additional category, which all pass with this change. Test failures of other tests are unrelated.)

It is still strange that architectures were only removed from buster repo recently. (It has been in LTS for a long time)

buster went EOL on 2022-09-10 and entered LTS back then.
LTS uses the same debian-security repos as normal security
updates but is only available for a limited set of architectures;
the others have stayed present but frozen, no longer updated.

But with the bookworm release and the t64 transition in sid,
mirrors ran out of disc space, so the frozen parts of buster
(anything other than the debian-security part for LTS arches)
have been copied to archive.d.o, then the buster parts for
n?n-LTS arches have been removed from the main mirror tree,
and shortly after 2024-06-30 when LTS will end, the remnants
will be removed from the main tree.

Unfortunately, this was a bit uncoordinated and the announcement,
while present, was not as clear as it could have been and did not
come sufficiently ahead of time. The relevant teams got sufficient
responses from irritated users already, so I hope they?ll improve
the next time ;-)

Thanks for detailed info. Removal of arches after running out of space is unfortunate. We could alternatively switch repo to archive.debian.org, but I like update to bullseye better. Hopefully history will not repeat itself with bullseye. :)

You?re welcome.

Hopefully history will not repeat itself with `bullseye`. :)

bullseye will EOL and enter LTS around 2024-08-14,
and its LTS will end around 2026-08-31.

I expect that some time between this, it?ll be copied to
archive.d.o, so from that time on, you could switch to
that except for the security updates.

LTS architectures are currently: i386, amd64, armhf, arm64
