     RTEMS: Improve GCC specification

     Add a start/end file specification if the -qrtems option is present.
     Allow targets to customize it.

     Support the standard -nodefaultlibs option.


             * config/rtems.h (RTEMS_STARTFILE_SPEC): Define if undefined.
             (RTEMS_ENDFILE_SPEC): Likewise.
             (STARTFILE_SPEC): Update comment.  Add RTEMS_STARTFILE_SPEC.
             (LIB_SPECS): Support -nodefaultlibs option.
             * config/or1k/rtems.h (RTEMS_STARTFILE_SPEC): Define.
             (RTEMS_ENDFILE_SPEC): Likewise.
             * config/rs6000/rtems.h (RTEMS_STARTFILE_SPEC): Likewise.
             (RTEMS_ENDFILE_SPEC): Likewise.
             * config/v850/rtems.h (RTEMS_STARTFILE_SPEC): Likewise.
             (RTEMS_ENDFILE_SPEC): Likewise.
