    H8/300: gas/testsuite: Use same architecture for gas and objdump in the FFxx1 testcase
    
    One of the H8/300-specific gas test cases fails as follows:
    
    [...]
    ../as-new     -o tmpdir/ffxx1-elf.o .../gas/testsuite/gas/h8300/ffxx1-elf.s
    Executing on host: sh -c {../as-new     -o tmpdir/ffxx1-elf.o .../gas/testsuite/gas/h8300/ffxx1-elf.s 2>&1}  /dev/null dump.tmp (timeout = 300)
    spawn [open ...]
    .../gas/testsuite/../../binutils/objdump  --prefix-addresses -dr tmpdir/ffxx1-elf.o > tmpdir/dump.out
    Executing on host: sh -c {.../gas/testsuite/../../binutils/objdump  --prefix-addresses -dr tmpdir/ffxx1-elf.o > tmpdir/dump.out 2>dump.tmp}  /dev/null  (timeout = 300)
    spawn [open ...]
    regexp_diff match failure
    regexp "^0+0412 <deloop>.*adds  #1,r1$"
    line   "00000412 <deloop> adds  #1,er1"
    FAIL: FFxx1
    [...]
    
    The source code uses "adds #1, r1", which is specific to H8/300, as it
    takes a 16-bit register as the operand. H8/300H and later variants, on the
    other hand, use 32-bit registers for this instruction, e.g. "adds #1, er1".
    Gas correctly assembles the H8/300 code, but objdump disassembles the
    resulting binary as H8/300H code because H8/300H is objdump's default
    architecture. This causes the error shown above. This patch fixes the issue
    by telling objdump which architecture to use.
