Patch rtems-rc-20000713-1-cvs.diff from Ralf Corsepius <corsepiu@faw.uni-ulm.de>

that is yet another multilib-related structual cleanup patch:

  Changes:
  * Make RTEMS_TEST_NO_PAUSE a tests/ subpackage specific option.
    - Remove RTEMS_TEST_NO_PAUSE from custom/*.cfg, targopts.h and
      cpuopts.h.
    - Add autoconf macros RTEMS_*_RTEMS_TEST_NO_PAUSE
      (aclocal/rtems-test-no-pause.m4).
    - Add RTEMS_*_RTEMS_TEST_NO_PAUSE support to sptests/configure.ins
      and tmtests/configure.in. These are the only subdirectories which
      currently apply RTEMS_TEST_NO_PAUSE.
    - Add autoconf-DEFS support to all test subpackages' configure.ins
      below tests/. I.e. AC_DEFINES now get explicitly propagated as
      preprocessor defines into Makefiles, cf. AM_CPPFLAGS in
      tests/*/*.am, instead of using a global config-files.
    - Remove NDEBUG from custom/*.cfg.

  * AC_DEFINE POSIX_API, ITRON_API and MULTIPROCESSING in
    exec/configure.in, only.
    - All other sources now should relay on the values from cpuopts.h
      and should not define them themselves.
    - Several related changes to many configure.ins

  * Bug-fixes to RTEMS_*_RTEMS_DEBUG macros (Actually workarounds to
    quoting bugs in autoconf).

  Notes:
    * This patch is rather immature and only tested for a small subset
      of BSPs (requires the tests to be enabled and therefore takes an
      tremendous amount of disc space and time.)
    * The patches to *cfg were generated by a script. Expect file
      formating changes :)
