bug#18177: chroot: "No such file or directory" message is so confusing

[T R]

   chroot: Failed to run command '/bin/bash': No such file or directory
   This needs to be updated with more information. It pops up when:

   1) The file is actually not there
   2) The file's dependent libraries are not there
   3) The file and its libraries are there, but it can't run for some
   reason

   This is too many causes to be indicated by such a brief and
   undocumented error message.
