[Bug 2077055] Re: s390-tools v2.34.0 FTBFS on oracular/s390x

[Frank Heimes]

Initial suspicion was that it could have been caused by gcc v14,
but all builds are with gcc-14, however, slightly different versions:
14-20240412-0ubuntu1 (noble)
14.1.0-5ubuntu1 (oracular, no FTBFS)
14.2.0-2ubuntu1 (oracular, FTBFS)

But the error msg seems to point to the linker (/usr/bin/ld), hence checking binutils:
2.42.90.20240720-2ubuntu1 (noble)
2.42-4ubuntu2 (oracular, no FTBFS)
2.43-2ubuntu1 (oracular, FTBFS)

Since there is a new version (2.43), looks like it's worth to follow the binutils path...
I've build and uploaded older binutils into a PPA and rebuild the s390-tools in the same, but no luck.
I used the same 2.42.90.20240720-2ubuntu1 that was used during the successful test build, but still failed to build:

Bug description:
  The (currently) latest s390-tools version 2.34.0 for oracular fails to build on s390x:
  https://launchpad.net/ubuntu/+source/s390-tools/2.34.0-0ubuntu1
  https://launchpadlibrarian.net/743774862/buildlog_ubuntu-oracular-s390x.s390-tools_2.34.0-0ubuntu1_BUILDING.txt.gz
  https://ubuntu-archive-team.ubuntu.com/proposed-migration/update_excuses.html#s390-tools
  The builds on other architectures (amd64, arm64 and ppc64el) are not affected (but are very small subsets anyway).

  It builds successful on noble:

  https://launchpadlibrarian.net/743599188/buildlog_ubuntu-noble-s390x.s390-tools_2.34.0-0ubuntu2.24.04.1_BUILDING.txt.gz

  and even built successful when a test build was done (prior to the upload) on Aug, 1st:
  https://launchpad.net/~fheimes/+archive/ubuntu/lp2073786/+sourcepub/16300146/+listing-archive-extra
  https://launchpadlibrarian.net/741871514/buildlog_ubuntu-oracular-s390x.s390-tools_2.34.0-0ubuntu1_BUILDING.txt.gz

  A new/updated package in the oracular archive that must have landed
  between 2024-08-01 and 2024-08-12 seem to have caused this build
  failure.

  The error is the build log is:
