Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

  This patch addresses a few minor issues and contains a few (minor)
  preparations for automake.

  * configure.in: Fix for handing c/src/tests subdirectory handling (FIX)
  * aclocal/rtems-top.m4:
    + Add TARGET_SUBDIR and --with-target-subdir (preparation of future
      enhancements for cross-compiling)
    + Activate RTEMS_ROOT handling (automake preparation)
  * automake/*.am: replace comments "#" with "##" so that comments won't
    get included into Makefile.in's anymore
  * c/update-tools/* automake support (NEW)
  * ./autogen update/enhancement (cf. ./autogen for details)

  After applying this patch please run:

    ./autogen
    cvs add c/update-tools/configure.in
    cvs add c/update-tools/Makefile.am
    cvs add c/update-tools/aclocal.m4
