Comment (by Chris Johns):

 Replying to [comment:12 Sebastian Huber]:
 > The RTEMS 4.11 release was in 2016. I added the
 _REENT_GLOBAL_STDIO_STREAMS option to Newlib in 2017, so this could be an
 RTEMS 4.11 only problem.

 Yes this is what I have discovered. I am preparing a patch to the newlib
 test to check assignements to `stdout` are working so we can spot any
 regressions. The check inspects the internal `__sdidinit` state but I feel
 this is worth doing because as you say it is fragile and difficult to

 I am preparing shell and test patches for 4.11 and 5 to fix `joel` scripts
 on both branches and a work round fix for 4.11. The 4.11 fix is a workable
 hack where `_sinit` is called in `newlib_create_hook`. Your solution is
 preferred however I do not think a new newlib on a release branch is a
 viable solution.
