Hi Christophe,

Oh it is supported for all targets, but only when the default cpu scan()
function is used.  (See bfd/archures.c:bfd_default_scan).  If the 
architecture provides its own scan function, then this needs to support
the <arch>:<machine> syntax in order for it to work.  (The AArch64 and ARM
architectures being obvious culprits in this case).

Yes - you are right.  We should update the documentation as well.  Do you want
to update the patch or shall I ?

Cheers
  Nick
