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 :)
