Re: Arm Kinetis: set_errno in nx_start with CONFIG_TLS_ALIGNED not set

[Gregory Nutt]

PR #1105 should eliminate the primary cause of the error: fs_fdopen() 
will not longer set the errno  variable.  The secondary error, the 
uninitialized stack description, is still a problem. 
Since the errno value was only set before fs_fdopen() failed, this means 
that you system will still not work.  It should not crash but it should 
not work either.  Now the fs_fdopen() calls will silently and 
mysteriously fail, perhaps with the only symptom being no standard I/O 
in the started tasks.
