Thanks a lot for this patch! Good to see that some people are active
maintaining elf2flt.

While you're in touch with people with elf2flt knowledge, could you
have a look at
http://lists.busybox.net/pipermail/buildroot/2019-June/253203.html ?
I'm pretty sure for someone with ARM/elf2flt knowledge it's fairly easy
to fix.

Thanks,

Thomas
