Fix _dl_deallocate_tls in !SHARED case
This patch seems needed in builds where
- SHARED is not defined (no shared lib support)
- and USE_TLS is set
Without this patch, static_dtv is free'ed.
See the following backtrace:

This backtrace is obtained while debugging tst-basic3 from the uclibc-ng nptl testsuite.
It aborts because of the assert in malloc:
