* config/mips/tm-mips.h (GDB_TARGET_IS_MIPS64): If not already
defined, define as 0. (FIX_CALL_DUMMY): Rewrite to remove presumption that host and target are similar. * config/mips/tm-idt.h (TARGET_BYTE_ORDER_SELECTABLE): Define. * config/mips/tm-idtl.h (TARGET_BYTE_ORDER_SELECTABLE): Define. * config/mips/tm-idt64.h (TARGET_BYTE_ORDER_SELECTABLE): Define. (BREAKPOINT): Remove definition. * config/mips/tm-idtl64.h (TARGET_BYTE_ORDER_SELECTABLE): Define. (BREAKPOINT): Remove definition. * config/mips/tm-mips64.h (GDB_TARGET_IS_MIPS64): Define with a value of 1, rather than without a value. * config/mips/tm-bigmips64.h (GDB_TARGET_IS_MIPS64): Likewise.
