/* md_parse_option
      Invocation line includes a switch not recognized by the base assembler.
      See if it's a processor-specific option.

      This routine is somewhat complicated by the need for backwards
      compatibility (since older releases of gcc can't be changed).
      The new options try to make the interface as compatible as
      possible with GCC.

      New options (supported) are:

	      -mcpu=<cpu name>		 Assemble for selected processor
	      -march=<architecture name> Assemble for selected architecture
	      -mfpu=<fpu architecture>	 Assemble for selected FPU.
	      -EB/-mbig-endian		 Big-endian
	      -EL/-mlittle-endian	 Little-endian
	      -k			 Generate PIC code
	      -mthumb			 Start in Thumb mode
	      -mthumb-interwork		 Code supports ARM/Thumb interworking
	      -mimplicit-litpool-dump    Dump literal pool on section change

      For now we will also provide support for:

	      -mapcs-32			 32-bit Program counter
	      -mapcs-26			 26-bit Program counter
	      -macps-float		 Floats passed in FP registers
	      -mapcs-reentrant		 Reentrant code
	      -matpcs
      (sometime these will probably be replaced with -mapcs=<list of options>
      and -matpcs=<list of options>)

      The remaining options are only supported for back-wards compatibility.
      Cpu variants, the arm part is optional:
              -m[arm]1                Currently not supported.
              -m[arm]2, -m[arm]250    Arm 2 and Arm 250 processor
              -m[arm]3                Arm 3 processor
              -m[arm]6[xx],           Arm 6 processors
              -m[arm]7[xx][t][[d]m]   Arm 7 processors
              -m[arm]8[10]            Arm 8 processors
              -m[arm]9[20][tdmi]      Arm 9 processors
              -mstrongarm[110[0]]     StrongARM processors
              -mxscale                XScale processors
              -m[arm]v[2345[t[e]]]    Arm architectures
              -mall                   All (except the ARM1)
      FP variants:
              -mfpa10, -mfpa11        FPA10 and 11 co-processor instructions
              -mfpe-old               (No float load/store multiples)
	      -mvfpxd		      VFP Single precision
	      -mvfp		      All VFP
              -mno-fpu                Disable all floating point instructions

      The following CPU names are recognized:
	      arm1, arm2, arm250, arm3, arm6, arm600, arm610, arm620,
	      arm7, arm7m, arm7d, arm7dm, arm7di, arm7dmi, arm70, arm700,
	      arm700i, arm710 arm710t, arm720, arm720t, arm740t, arm710c,

     If the address stored at .Laaa is that of a symbol which has the
     Thumb_Func bit set, then the linker will arrange for this address
     to have the bottom bit set, which in turn would mean that the
     address computation performed by the third instruction would end
     up with the bottom bit set.  Since the ARM is capable of unaligned
     word loads, the instruction would then load the incorrect address
