[PATCH] Microblaze: cleanup

[Michael Eager <eager at eagercon dot com>]

Microblaze only supports gas.  Remove old references
to microblaze assembler.

On microblaze branch.

2009-09-17  Michael Eager <eager@eagercon.com>

* config/microblaze/microblaze.h: MICROBLAZE_AS_ASM_SPEC, 
SUBTARGET_MICROBLAZE_AS_ASM_SPEC, GAS_ASM_SPEC,
SUBTARGET_ASM_OPTIMIZING_SPEC, SUBTARGET_ASM_SPEC,
SUBTARGET_ASM_DEBUGGING_SPEC, microblaze_as_asm_spec, gas_asm_spec,
subtarget_microblaze_as_asm_spec, subtarget_asm_optimizing_spec,
subtarget_asm_debugging_spec, linker_endian_spec: Remove.

Checked in.
