Patch rtems-rc-20000104-17.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>

that addresses the librdbg/rpcgen related problems:

    Changes:
        * All rpcgen generated files are now kept inside of the source tree
        * Fix librdbg/configure to correctly detect presence of rpcgen and awk
        * Use rpcgen -m to generated remdeb_svc.c
        * Remove msgout/_msgout from awk.svc
        * minor cleanups to librdbg/configure.in

    ATTENTION --- IMPORTANT:

        * With keeping rpc-generated files pre-build inside of the source tree,
          you as the packager of RTEMS have to ensure that timestamps are
          correctly set up: The generated files must not be older than the *.x
          files.
        * This is extraordinarily important when
            - putting the package on read-only media
            - after checking out from CVS
            - after modifications to the *.x files
        * If one of the *.x files is modified you have to either
            - build for i386/pc386 and powerpc/mcp750
            - or to invoke the same rpcgen calls as the
              librdbg/src/<cpu>/<bsp>/Makefile.am do manually
              before checking-in the files to CVS.

    Proposal:

    We could add something to bootstrap for touching the rpcgen-generated
    sources and/or to manually regenerate them.

    NOTE FROM JOEL:

    Ralf proposed modifying bootstrap to handle rpcgen.  I think this
    is the best solution as it is something already done in the
    snapshot procedure.
