Comment 1 Aníbal Limón 2015-03-12 17:44:22 UTC 
Partial solution was implement to provide support in autoconf for detect when build is x32,

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=alimon/kexec-tools-x32-abi

Some issues still exist when try to exec:

# kexec -l vmlinux

These issues are related to ELF read's.

Can you provide me the steps for testing?
