--- Comment #17 from Chris Johns <chrisj at rtems dot org> ---
I see the same issue when building tools for RTEMS using the RSB. I have
collected the posted parts in a patch and attached it to a ticket in RTEMS's
trac:

https://devel.rtems.org/ticket/3171

An RTEMS tools build now fails with:

../../../../gcc-7.2.0/libstdc++-v3/libsupc++/atexit_thread.cc:27:10: fatal
error: bits/gthr.h: No such file or directory                                   
 #include "bits/gthr.h"                                                       
          ^~~~~~~~~~~~~                                                       

so there seems to be more issues.
