(SUBSUBTARGET_EXTRA_SPECS): Provide empty default. * config/arm/unknown-elf.h (UNKNOWN_ELF_STARTFILE_SPEC): Renamed from STARTFILE_SPEC so that it can be referenced in an override. (STARTFILE_SPEC): Use UNKNOWN_ELF_STARTFILE_SPEC. (UNKNOWN_ELF_ENDFILE_SPEC): Renamed from ENDFILE_SPEC so that it can be referenced in an override. (ENDFILE_SPEC): Use UNKNOWN_ELF_ENDFILE_SPEC. * config/arm/bpabi.h (BPABI_LINK_SPEC): Renamed from LINK_SPEC so that it can be referenced in an override. (LINK_SPEC): Use BPABI_LINK_SPEC. * config/arm/eabi.opt (File): New.
