GCCC 14 introduced a linking warning about not knowing which __sync_synchronize implementation to use. The BSPs impacted are updated in this commit. The suggested correction is to use -specs to pick up a GCC specific specs file which changes __sync_synchronize to the desired implementation __sync_synchronize_MECHANISM. Using this solution ties the code to GCC 14+ since the spec files are not in GCC 13. This solution maps __sync_synchronize to a RTEMS specific __sync_synchronize implementation which avoids using of a GCC extension and requiring GCC 14+, Closes #5268
