I am pretty sure the filesystem and busybox are big endian. I can see
the following print out when the filesystem is built for big endian
mode. 
"Swapping filesystem endian-ness"
Though I don't know if there is a command to check the endianess of a
filesystem directly.

And below is the header info of the busybox showing it is a big endian
object.
readelf -h busybox-1.14.3/busybox
