/* This structure contains everything that BFD knows about a target.
24
   It includes things like its byte order, name, what routines to call
25
   to do various operations, etc.  Every BFD points to a target structure
26
   with its "xvec" member.
27
 
28
   There are two such structures here:  one for big-endian machines and
29
   one for little-endian machines.   */
