undefined symbols in /lib/libthread_db.so.1

[Jack Howarth]

   On debian ppc sid, using our debian glibc cvs 2.3.2-1 packages
with a cvs pull of 05-16-03, I am seeing some undefined symbols
in /lib/libthread_db.so.1...

ldd -r /lib/libthread_db.so.1
        libc.so.6 => /lib/libc.so.6 (0x0fe80000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x08000000)
undefined symbol: ps_pglobal_lookup     (/lib/libthread_db.so.1)
undefined symbol: ps_pdwrite    (/lib/libthread_db.so.1)
undefined symbol: ps_lsetfpregs (/lib/libthread_db.so.1)
undefined symbol: ps_getpid     (/lib/libthread_db.so.1)
undefined symbol: ps_lsetregs   (/lib/libthread_db.so.1)
undefined symbol: ps_pdread     (/lib/libthread_db.so.1)
undefined symbol: ps_lgetfpregs (/lib/libthread_db.so.1)
undefined symbol: ps_lgetregs   (/lib/libthread_db.so.1)

Any idea of this is expected behavior and if so which lib
is defining these symbols?
