(LIB_SPEC): Use proper linker script for bf561. Error if no mcpu option. * config/bfin/bfin.c (bfin_cpu_type): Set to BFIN_CPU_UNKNOWN. (cputype_selected): Remove. (bfin_handle_option): Don't use cputype_selected. (override_options): When no mcpu option, enable all workarounds. Don't use bfin_workarounds. * config/bfin/bfin.h (DRIVER_SELF_SPECS): Don't set default processor type. (DEFAULT_CPU_TYPE): Don't define.
