    Rename SUBTARGET_CC1_SPEC to OS_CC1_SPEC
    
    This change resolves a naming conflict introduced by the recently added
    SUBTARGET_CC1_SPEC to gcc.cc.  Some targets (mips and loongarch) aready used
    a SUBTARGET_CC1_SPEC define.  Rename the define used by gcc.cc to OS_CC1_SPEC.
    
    gcc/ChangeLog:
    
            * config/rtems.h (SUBTARGET_CC1_SPEC): Rename to...
            (OS_CC1_SPEC): ...this.
            * gcc.cc (SUBTARGET_CC1_SPEC): Rename to...
            (OS_CC1_SPEC): ...this.
