I think you could do this with file or readelf, although I am not
sure if this is the best way.

file /bin/cp
/bin/cp: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped


readelf -h /bin/cp
ELF Header:

  Data:                              2's complement, little endian
  Version:                           1 (current)
