>Description:
Building a powerpc64 gdb fails while linking with
undefined references:

#      link  gdb/gdb
[...]
/Users/dennis/NetBSD/5.0-current/src/gnu/usr.bin/gdb6/libgdb/obj/libgdb.a(ppcnbsd-nat.o):(.toc+0x18): undefined reference to `nbsd_pid_to_exec_file'
/Users/dennis/NetBSD/5.0-current/src/gnu/usr.bin/gdb6/libgdb/obj/libgdb.a(ppcnbsd-nat.o):(.toc+0x58): undefined reference to `ppcnbsd_gregset'
/Users/dennis/NetBSD/5.0-current/src/gnu/usr.bin/gdb6/libgdb/obj/libgdb.a(ppcnbsd-nat.o):(.toc+0x78): undefined reference to `ppcnbsd_fpregset'
collect2: ld returned 1 exit status

*** Failed target:  gdb

The missing functions are present in the sources, in
src/gnu/dist/gdb6/gdb/ppcnbsd-tdep.c.

>How-To-Repeat:
Do a:

    MACHINE=macppc64 ./build.sh distribution
>Fix:
I believe the problem is that the generated build
configuration files in src/gnu/usr.bin/gdb6/arch/powerpc64/
are out of date and need to be regenerated.  While
I apparently lack the right juju to follow the instructions
for doing this myself, I know that copying the more
recently made versions of config.h, defs.mk and init.c
from the powerpc/ directory into powerpc64/ made the
problem go away so I strongly suspect that making
new files the proper way will do so too.

State-Changed-When: Sat, 27 Mar 2010 20:18:40 +0000
State-Changed-Why:
i couldn't get mknative-gdb to run in the very short amount of time i gave it,
but copying the powerpc fails as dennis suggests works just fine for me, so
i've done that for now.

someone hopefully can re-generate them properly and then close this PR :)

 Modified Files:
 	src/gnu/usr.bin/gdb6/arch/powerpc64: config.h defs.mk init.c

 Log Message:
 copy across the powerpc versions of these files for now.  should use
 mknative-gdb to generate these, but my initial attempt failed and
 these ones seem to be about what i'd expect anyway.
 suggested by dennis.c.ferguson@gmail.com in PR#43043.
