        Remove COFF support from i?86-pc-sco3.2v5.
        * i386/sco5.h (PREFERRED_DEBUGGING_TYPE): Change to Dwarf II.
        (TARGET_ELF): Now always true.
        (SUBTARGET_SWTICHES: )Remove -mcoff.

        * i386/t-sco5 (MULTILIB_OPTIONS, MULTILIB_DIRNAMES,
        MULTILIB_EXCEPTION): Nuke coff.
        (CRTSTUFF_T_CFLAGS_S):  Deleted.
        (TARGET_LIBGCC2_CFLAGS): Added.
