Log Message:
-----------
thanks netbsd 5 ... they partially implemented TLS support so it compiles and
links, but will simply crash at runtime. (gives __tls_get_addr() runtime link
failure on library linkage) change the test to also run the test, not just
compile it for the __thread test only to catch this failure. pthread fallback
should hopefully still work.
