I've found that the X86 compiled readelf on the host developement
linux machine reads the arm elf binaries ok. e.g. on my host developement
box...

:~/export/cfdisk$ file bin/busybox
bin/busybox: ELF 32-bit LSB executable, ARM, version 1, for GNU/Linux 
2.4.3, dynamically linked (uses shared libs), stripped
:~/export/cfdisk$ readelf -d bin/busybox
