warning: Unable to find dynamic linker breakpoint function.

[Manoj Iyer <manjo@austin.ibm.com>]

latest cvs GDB gives me a warning that it cannot set breakpoint in dynamic
linker, but GDB from RH sources works ok. Sometihng in GDB changed? I saw
a similar discussion for AMD64 last year (between Daniel and Adam
Richard), but it does not make clear why this would happen on cvs version
and not on older versions of GDB.

Platform: ppc64
OS: RH 4.
