Patch rtems-rc-4.5.0-21.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>

which splits the current monolithic specs files into a sequence of
subparts.  These can be concatenated togather to make a the whole .spec
file.  This cleans up the maintenance problem of having "all languages"
and a "C/C++ only" gccnewlib spec files.  Plus it should make it easier
to produce variants like the gdb-m68k-bdm which require special hackery. :)
Ralf's comments:

  It addresses the way *.spec.in get composed inside of the source
  tree.

  Changes:
    * Each spec.in is broken into several files (*.add), one *.add file
      per sub-package.
    * Each Makefile.am composes spec.ins from the *.add files
    * Removal of redundant automake support files.
    * Default value for BuildRoot changed to /tmp/<spec-file-name>
    * %clean stage added to *specs

  Advantages (IMHO).
    * The *.add files are easier to adminstrate and more flexible in
      comparison to the former *.specs.ins.
    * gccnewlib_c_only.spec.in now is composed from the same sources as
      gccnewlib.spec.in (less errors)
    * If using the default BuildRoot --clean now deletes all files that
      were generated while building.

  Notes:
    * rtems.spec.in has not yet been adapted to the scheme used for the
      other *spec.ins
    * Except for cosmetical changes the internals of the  *.spec files
      should not have changed.

  To Apply:
    cvs rm -f scripts/binutils/binutils.spec.in
    cvs rm -f scripts/gccnewlib/gccnewlib.spec.in
