Bug Description

When testing the next upload merging changes from Debian I've encoundered the following failure:

https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4017/+build/19642918/+files/buildlog_ubuntu-groovy-armhf.glibc_2.31-2ubuntu1~rbalint2_BUILDING.txt.gz :

The same command passed with gcc-9 in the Ubuntu archive:

...

I think libgcc.a should not use VFP register arguments if we still want to allow using -mfloat-abi=soft this way, but I'm also checking a workaround in glibc to not build libc_pic.* so this error would not be hit. (libc-pic is not shipped in Debian anymore and the merge bring this change in to Ubuntu.)

    libnss-nis*, rpcsvc-proto, libtirpc-dev and libnsl-dev (LP: #1895632)
  * XFAIL time/tst-cpuclock1 (LP: #1895687)

    It replaces the development files for the new libnsl library replacing the
    one shipped by glibc.
  * Don't check symbols of libnss_nis.so and libnss_nisplus.so libraries.
    They are not shipped in glibc 2.32

[ Balint Reczey ]
  * Merge from Debian unstable
    - debian/patches/any/submitted-selinux-deprecations.diff: proposed patch to
      ignore the selinux deprecations introduced in libselinux (>= 3.1), fixing
      an FTBFS. (LP: #1887919)
    Remaining changes:
    - Enable libc6{,-dev}-armel on armhf and libc6{-dev}-armhf on armel.
    - Heavily mangle the way we do service restarting on major upgrades.
    - Build amd64 with -O3, and build ppc64 variants (both 64-bit and 32-bit)
      with -O3 -fno-tree-vectorize.
    - Build generic i386 flavour with -mno-tls-direct-seg-refs for Xen.
    - Drop the libc6-xen flavour, as the above change covers Xen's needs.
    - Enable systemtap support, which is currently disabled in Debian.
    - Don't build libc-l10n, its contents get stripped for language-packs.
    - Drop libc-bin manpages Recommends to Suggests to keep it in standard.
    - Revert dropping the ldconfig wrapper, as we still have a lot of
      packages that don't ship a trigger but instead call in postinst.
    - Use DH_COMPAT=8 for dh_strip to fix debug sections for valgrind.
    - Mangle locales package to support Ubuntu language packs seamlessly.
    - Relax some expected test failures for our infrastructure's quirks.
    - Let nptl/tst-stack4 fail, as it's been racing on several architectures.
    - Copy the fully conditionalized x86 variant for math-vector-fortran.h
      to /usr/include/finclude. On all architectures.
    - Backport x86 CET patches from the trunk.
    - Ship arm64 variant with LSE support in libc6-lse
    - debian/sysdeps/{amd64/i386/x32}.mk: Enable Intel Control Flow
    Dropped changes:
    - Build i386 variants as -march=i686
    - debian/patches/git-updates.diff: update from upstream stable branch.
  * debian/gbp.conf: Add initial configuration
  * debian/debhelper.in/libc.preinst: Fix setting LDCONFIG_NOTRIGGER
    (LP: #1889190)
  * Build-depend again on g++-10-multilib on armel and armhf which were lost in the merge
    (LP: #1889069)
  * debian/control.in/main: Add Vcs-* pointing to Ubuntu packaging repository
  * Don't handle false positive stringop-overflow warnings as errors on ppc64el
  * Fall back to calling nanosleep syscall when __clock_nanosleep returns EINVAL
    (LP: #1871240)
  * debian/testsuite-xfail-debian.mk: XFAIL stdlib/tst-strtod-round on riscv64
