or the
     output file (*note BFD::).  Using 'OUTPUT_FORMAT(BFDNAME)' is
     exactly like using '--oformat BFDNAME' on the command line (*note
     Command Line Options: Options.).  If both are used, the command
     line option takes precedence.

     You can use 'OUTPUT_FORMAT' with three arguments to use different
     formats based on the '-EB' and '-EL' command line options.  This
     permits the linker script to set the output format based on the
     desired endianness.

     If neither '-EB' nor '-EL' are used, then the output format will be
     the first argument, DEFAULT.  If '-EB' is used, the output format
     will be the second argument, BIG.  If '-EL' is used, the output
     format will be the third argument, LITTLE.

     For example, the default linker script for the MIPS ELF target uses
     this command:
          OUTPUT_FORMAT(elf32-bigmips, elf32-bigmips, elf32-littlemips)
     This says that the default format for the output file is
     'elf32-bigmips', but if the user uses the '-EL' command line
     option, the output file will be created in the 'elf32-littlemips'
     format.

'TARGET(BFDNAME)'
     The 'TARGET' command names the BFD format to use when reading input
     files.  It affects subsequent 'INPUT' and 'GROUP' commands.  This
     command is like using '-b BFDNAME' on the command line (*note
     Command Line Options: Options.).  If the 'TARGET' command is used
     but 'OUTPUT_FORMAT' is not, then the last 'TARGET' command is also
     used to set the format for the output file.  *Note BFD::.
