[Bug]: ELF incorrect note alignment value for ABI-tag.

[gdahlm]

Note: This does not relate to NVIDIA Container Toolkit as their ELF binaries have the correct offset.

Describe the bug
.note.ABI-tag in distributed ELF64 binaries on Ubuntu e.g. /usr/lib/x86_64-linux-gnu/libnvidia-container.so.1 have an alignment of 32 when it should be 4 (or 8). This results in an unreadable note and an error on tools like readelf and verification of installed objects/binaries with various tools.

To Reproduce

Try to read the note with readelf (will work with any ELF file):

$ readelf -j .note.ABI-tag /usr/lib/x86_64-linux-gnu/libnvidia-container.so.1

Displaying notes found in: .note.ABI-tag
readelf: Warning: Corrupt note: alignment 32, expecting 4 or 8

View the problem by looking at headers:

$ readelf -S /usr/lib/x86_64-linux-gnu/libnvidia-container.so.1
There are 29 section headers, starting at offset 0x305d0:

Section Headers:
  [Nr] Name              Type             Address           Offset

  <snip>

Expected behavior

It should return the ABI-tag note without error like nvidia-ctk:

$ readelf  -j .note.ABI-tag /usr/bin/nvidia-ctk

Displaying notes found in: .note.ABI-tag
