that is yet another multilib-related structual cleanup patch:
Changes:
* Make RTEMS_DEBUG a global per-cpu configuration option
* Remove RTEMS_DEBUG from targopts.h
* Add a global --enable-rtems-debug option disabled by default.
* Add RTEMS_DEBUG to cpuopts.h
* Remove all references to RTEMS_DEBUG from custom/*.cfg
Notes:
* RTEMS_DEBUG is set in c/src/exec/configure.in only
(RTEMS_CHECK_RTEMS_DEBUG) and should be defined in cpuopts.h only.
BSPs should not redefine it, but use the value being provided by
cpuopts.h.
=> With multilibs, users have to choose: Either enable RTEMS_DEBUG
for all BSPs and CPU_MODELs of a cpu or not.
* Only few BSPs had RTEMS_DEBUG enabled, therefore I set the default
to disabled.
* This patch influences the per-BSP building scheme. Existing BSPs
which set RTEMS_DEBUG in their make-target-options rule might have
problems at runtime.
