* m68k.h (TARGET_SWITCHES): -mcpu32 now clears MASK_68881.

        (MACHINE_STATE_m68010_up): Replaced __mc68332__ with __mcpu32__.
        * m68k/m68k-none.h(CPP_FPU_SPEC): Update relative to TARGET_SWITCHES.
        (CPP_SPEC, ASM_SPEC, CC1_SPEC): Likewise.
        (CPP_SPEC): -m68332 defines both __mc68332 and __mcpu32__.
        * m68k/t-m68kbare (MULTILIB_OPTIONS): Add mcpu32.
        (MULTILIB_MATCHES): -m68332 now uses mcpu32 libraries, not m68000.
        (MULTILIB_EXCEPTIONS): Don't build 68881 libraries for m68000,
        mcpu32 or m5200.
        * longlong.h: Replace __mc68332__ with __mcpu32__.
