commit c484da9087632f2f1b4ab5a6cae4efcd09436d1d
Author: Sergey Bugaev <bugaevc@gmail.com>

elf: Remove THREAD_GSCOPE_IN_TCB
All the ports now have THREAD_GSCOPE_IN_TCB set to 1. Remove all
support for !THREAD_GSCOPE_IN_TCB, along with the definition itself.

This normally is done using the thread register which points
