devel/pango and devel/atk need the same workaround as in devel/glib2 to
cope with lack of "gtkdoc-rebase" program.

In addition, net/Orbit2 and devel/GConf need the same treatment.

As more offending packages are discovered, they will be appended to this
PR.
>How-To-Repeat:
On MacOS X, attempt to build a package that has any of:

  devel/atk
  devel/pango
  devel/GConf
  net/Orbit2

as a dependency.  Example:  multimedia/mplayer
>Fix:
Add the following to the Makefile of offending dependency packages:

.if ${OPSYS} == "Darwin" || ${OPSYS} == "SunOS"
TOOLS_NOOP+=            gtkdoc-rebase
.endif
