[Patch]: Check __gthread_setspecific return

[Ryan Mansfield]

Hi,

Underlying pthread_setspecific can return non-zero with ENOMEM or EINVAL.
2014-12-02  Ryan Mansfield  <rmansfi...@qnx.com>

        * emutls.c (__emutls_get_address): Check __gthread_setspecific 
returns.

OK?

Regards,

Ryan Mansfield
