Annoying objcopy message

[Nick Clifton]

Hi H.J.

No.

> What does it do with "architecture?"

Nothing.  There is no concept of an architecture associated with a
"binary" file, (or an "ihex" file for that matter).

> The most importantly, can "binary" represent architecture UNKNOWN?

No - there is no such architecture as "UNKOWN".  The warning message you
are seeing is unhelpful.

  objcopy -Iihex xxx -Obinary xxx.gz
  objcopy: Warning: Output file cannot represent architecture UNKNOWN!

This should really be:

  objcopy -Iihex xxx -Obinary xxx.gz

(ie no warning at all).  Since both the input format and the output
format do not have architectures associated with them, there is
nothing to warn about.
