SRU: update binutils to the 2.38 branch and ignore lto-wrapper warnings

[Matthias Klose]

The tests sometimes fail with spurious lto-wrapper warnings and let the build fail. Ignore these warnings, they don't matter for the test outcome.

Also apply four fixes from the binutils 2.38 branch:

  * SRU: LP: #1982105. Update from the binutils 2.38 branch:
    - Fix PR ld/29435: elf: Reset alignment for each PT_LOAD segment.
    - PowerPC64 pcrel got relocs against local symbols.
    - Fix PR ld/27998: i386: Don't allow GOTOFF relocation against
      IFUNC symbol for PIC.
    - Fix PR ld/29377: x86: Properly check invalid relocation against
      protected symbol.
  * Ignore lto-wrapper warnings when running the testsuite.

https://sourceware.org/bugzilla/show_bug.cgi?id=27998
https://sourceware.org/bugzilla/show_bug.cgi?id=29377

All changes are already in 2.39 in kinetic, and 2.40 in lunar. The changes come with test cases, and pass when running the testsuite.

Hello Matthias, or anyone else affected,

Accepted binutils into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/binutils/2.38-4ubuntu2.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

This is a specific case, so the only thing I expect for this upload is for the autopkgtests to pass (+ the obvious added unit-tests for all the aforementioned issues listed as fixed).

[Ubuntu SRU Bot (ubuntu-sru-bot)]

All autopkgtests for the newly accepted binutils (2.38-4ubuntu2.3) for jammy have finished running.
The following regressions have been reported in tests triggered by the package:

crash/8.0.0-1ubuntu1 (amd64, arm64, s390x)
fpc/3.2.2+dfsg-9ubuntu1 (arm64)
linux-hwe-5.19/5.19.0-46.47~22.04.1 (arm64, armhf)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].

Thank you!

after retries, all the autopkg tests pass, binutils test results don't show regressions.

[Łukasz Zemczak (sil2100)]

The verification of the Stable Release Update for binutils has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
