>Description:
When doing a macppc64 build, linking gdbtui fails with
a bunch of undefined references to functions mostly
named sim_something(), i.e.:

#      link  gdbtui/gdbtui
[...]

*** Failed target:  gdbtui

>How-To-Repeat:
Do a:

    MACHINE=macppc64 ./build.sh distribution
>Fix:
The functions are all supposed to be in gdb's libsim.a,
which isn't included in the link.  The reason for this
is that while libsim.a's Makefile is willing to make
the library for powerpc64, gdbtui's Makefile forgets to
include the library when building for powerpc64.  The following
patch to src/gnu/usr.bin/gdb6/gdbtui/Makefile repairs the oversight.
