            Bug ID: 25511
           Summary: unknown program header entry type 0x6474e553
           Product: elfutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: general
          Assignee: unassigned at sourceware dot org
          Reporter: amerey at redhat dot com
                CC: elfutils-devel at sourceware dot org
  Target Milestone: ---

On ubuntu 19.10 x86_64 run-strip-strmerge.sh, run-elflint-self.sh and
run-reverse-sections-self.sh all with the same error: "program header entry 9:
unknown program header entry type 0x6474e553". 

This is caused by the inclusion of a new ELF program header PT_GNU_PROPERTY in
newer binutils. For more information see
https://bugzilla.redhat.com/show_bug.cgi?id=1748802

Steps to reproduce on ubuntu 19.10 x86_64: `./configure; make; make check
TESTS='run-strip-strmerge.sh run-elflint-self.sh run-reverse-sections-self.sh'`

I requested some more background information on this:
https://sourceware.org/ml/gnu-gabi/2020-q1/msg00000.html

But since it is now emitted in production binaries lets handle it as is for
now.
