What synax I should use for this option ?
'info objcopy' statest :
`--alt-machine-code=INDEX'
If the output architecture has alternate machine codes, use the
INDEXth code instead of the default one.  This is useful in case a
machine is assigned an official code and the tool-chain adopts the
new code, but other applications still depend on the original code
being used.
