Thanks Laurentiu - I did validate that the interp section looks to be
0x1000 bytes for the qemu-* binaries:

$
/usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/bin/qemu-system-arm
--version
QEMU emulator version 1.6.1, Copyright (c) 2003-2008 Fabrice Bellard

$ readelf -S
/usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/bin/qemu-system-arm

There are 29 section headers, starting at offset 0x5a14b8:

Section Headers:

  [ 3] .note.gnu.build-i NOTE             0000000000001290  00001290
...

If anyone has any other suggestions to test, I will gladly attempt them
before posting a v2.

Cheers!
