Hello Adam, or anyone else affected,

Accepted binutils into xenial-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/binutils/2.26.1-1ubuntu1~16.04.8 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 and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. 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)

Title:
  [SRU] Patch power9-001.diff breaks IFUNC on ELFv1

Status in binutils package in Ubuntu:
  Invalid
Status in binutils source package in Xenial:
  Fix Committed

Bug description:
  [ SRU Justification ]
  As per comment #4 in 
https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/1655181 the undefined 
weak fix should not have been backported because it breaks IFUNC on ELFv1, and 
can't be fixed without a much larger backport from 2.27.  This patch breaks 
glibc builds on PPC64 ELFv1.

  See also https://sourceware.org/bugzilla/show_bug.cgi?id=20472

  I will be pushing this upload via the ubuntu-security-proposed PPA, as
  this regression also exists in security and if we ever want to do a
  glibc security update, we need the fix there as well.

  [ Test Case ]
  See that glibc now builds on powerpc in xenial, when it didn't with the 
previous version.

  [ Regression Potential ]
  We lived fine without this patch before, and will do again in the future.  
Removing it fixes ELFv1 glibc builds (and presumably anything else that uses 
IFUNC), but should have no other obvious impact.
