- Subject: PowerPC64 TLS optimization fix
When linking with --no-tls-optimize the linker doesn't generate a call
or long branch stub to __tls_get_addr in some circumstances, giving:
relocation truncated to fit: R_PPC64_REL24 against symbol `__tls_get_addr'
* elf64-ppc.c (ppc64_elf_size_stubs): Correct condition under
which __tls_get_addr calls will be eliminated.
