From ARM (which you invoked):

This option can also be used for ARM architectures to force the disassembler
to interpret all instructions as Thumb instructions by using the switch
'--disassembler-options=force-thumb'. This can be useful when attempting
to disassemble thumb code produced by other compilers.
