Nearly, but not quite.

This should be in SUBTARGET_ASM_FLOAT_SPEC.

Also, the order of your include files looks suspect (in config.gcc); I 
think it should be

dbxelf.h elfos.h arm/rtems-elf.h rtems.h arm/elf.h arm/aout.h arm/arm.h

Note that arm/unknown-elf.h should not be included -- it's for an unknown 
OS environment and is bogus in this instance (if there really is a 
definition in this file that you rely on, copy it to arm/rtems-elf.h).

Once you have the include order correct it won't be necessary to keep 
undefining macros before defining variants.
