Jonas Devlieghere 79ff112122 [Sparc] Include __tls_get_addr in symbol table for TLS calls to it 
Global Dynamic and Local Dynamic call relocations only implicitly
reference __tls_get_addr; there is no connection in the ELF file between
the relocations and the symbol other than the specification for the
relocations' semantics. However, it still needs to be in the symbol
table despite the lack of explicit references to the symbol table entry,
since it needs to be bound at link time for these relocations, otherwise
any objects will fail to link.

For details, see https://sourceware.org/bugzilla/show_bug.cgi?id=22832.
