Comment (by Chris Johns):

 We need to add support to din the TSL base for a thread for each
 architecture:

 * aarch64
 * arm
 * bfin
 * i386
 * lm32
 * m68k
 * mips
 * moxie
 * powerpc
 * riscv
 * sparc
 * v850

 == AARCH64
 {{{
 static void* rtems_rtl_tls_get_base (void) {
   intptr_t value;
   __asm__ volatile (
     \"mrs %0, TPIDR_EL0\" : \"=&r\" ( value ) : : \"memory\"
   );",
   return value;
 }
 }}}
