Minor conditionals to enable building Scheduler Simulator on GNU/Linux

  • rtems/score/assert.h: Scheduler Simulator uses glibc assert.h on GNU/Linux. This will likely need to be adjusted more for other host compilers and C libraries. Also disable _Assert_Not_reached() because some of these paths do actually return to the called on the Scheduler Simulator.
  • basedefs.h: Do not use noreturn attribute when on Scheduler Simulator. Paths which context switch can return to the command interpreter on the Scheduler Simulator.
  • Property mode set to 100644
