Apparently there is a mismatch between the expected and the effective layout of "struct stat". Are you sure that when compiling busybox, the same (or a compatible) definition of "struct stat" was used as in the target library? You could also print "sizeof statbuf.st_ino" and "offsetof(struct stat, st_mode)" or a dump of the bytes in "statbuf". Or you could try if changing the option CONFIG_LFS makes any difference.
Another approach: You wrote that the dynamic busybox works on your aboriginal system image; you could copy the shared object from there to your target.
