[RFC,11/22] Add Infinity THREAD_SELF macros to sysdeps/nios2/nptl/tls.h
Commit Message
This commit adds Infinity THREAD_SELF macros for nios2.
It's possible for this platform to put the Infinity macros before
libthread_db's DB_THREAD_SELF, and define DB_THREAD_SELF in terms
of the Infinity values, but I wasn't sure if it would be appropriate.
