Good question, there seems to be some support missing. For example for 
arm/xilinx_zynq_a9_qemu:

Breakpoint 7, Init (ignored=2118804) at 
/home/EB/sebastian_h/src/rtems/testsuites/samples/fileio/init.c:1169
1169      TEST_BEGIN();
(gdb) watch _tls_errno
Cannot find thread-local variables on this target
(gdb) p _tls_errno
Cannot find thread-local variables on this target
