Patch rtems-rc-4.5.0-7-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>.

The patch contains:

  * Many small cleanups wrt. make VARIANT=[DEBUG|PROFILE] support
  * several modifications to make/custom/*.cfg
  * Merger with the mvme2307.cfg you had posted two weeks ago (Please
    check it, I did not check it against to version you posted today).
  * Added a check to the toplevel configure.in to refuse building inside
    of the source tree.
