(MOTOROLA): Define this.

(VERSADOS): This the name of the DPX2 assembler. Define this in case.
(USG): Define this.
(SGS_NO_LI): define this to suppress jump table usage.
(TARGET_DEFAULT): Define this to 3 inside the conditional USE_GAS since
bitfields do not work a clean way on DPX2.
(EXTRA_SECTIONS, EXTRA_SECTION_FUNCTIONS, SELECT_SECTION, SELECT_RTX_SECTION):
#undef these.
(READONLY_DATA_SECTION): Define to data_section.
(*_ASM_OP, ASM_OUTPUT_*): Define these accordingly to the native assembler
syntax.
(LONG_DOUBLE_TYPE_SIZE): Set to 64 to not use XFmode.
(REAL_ARITHMETIC): Define this to use the software floating point emulator.
(JUMP_TABLES_IN_TEXT_SECTION): Define this to 1.
(FUNCTION_PROLOGUE, FUNCTION_EPILOGUE): Override m68k.h default.
(ASM_OUTPUT_ASCII): add a new variable to take care of the lentgh of the
operand field which must be < 80 chars.
(PRINT_OPERAND_ADDRESS): Override m68k.h default.
(PUT_SDB_TYPE): Output type in decimal.
(PUT_SDB_FUNCTION_[START|END]): Override sdbout.c default.
(PUT_SDB_BLOCK_[START|END]): Override sdbout.c default.
