The kbuild machinery for building the linux kernel always leaves behind
a file which contains the actual shell command that was used to 'make'
any [sub-]target that was made successfully.  The name of this extra file
is:  .<target>.cmd .  So if making b43.o was successful (i.e., compiling b43.c
worked), then there will be a file  .b43.o.cmd   which has the shell command
that did it.  Find some succesful compilation of a <driver>.o, and look
at the  .<driver>.o.cmd  file.

Then consult the documentation "info gcc" for:
   _Machine Dependent Options_
   _ARM Options_
   -mstructure-size-boundary=N
