On ia64 we never call _rtld_allocate_tls():

itanium% ldd ./hello
ldd: ./hello: not a dynamic executable
itanium% gdb ./hello
GNU gdb 6.1.1 [FreeBSD]
*snip*
(gdb) b _rtld_allocate_tls
Breakpoint 1 at 0x20000000000004a0
(gdb) run
Starting program: /nfs/home/marcel/hello
Hello world!

Program exited normally.
(gdb) b _init_tls
Breakpoint 2 at 0x2000000000000640
(gdb) run
Starting program: /nfs/home/marcel/hello

Breakpoint 2, 0x2000000000000640 in _init_tls ()
(gdb) c
Continuing.
Hello world!

Program exited normally.
(gdb) quit
