Log message:
Teach wxGTK24 about DragonFly.

Log message:
GTK2 no longer depends on libpangox as of GTK2 version 2.8.x.
However, wxGTK24 still depends on libpangox.
Copy PANGOX test from unicode section of configure script.
This causes libpangox to show up as a dependency in pkg-config.
This fixes build problems with programs depending on wxGTK24.
This addresses PR#31536.

Log message:
- Patch from Thomas Klausner to not install the local files, which would
  conflict with the wxGTK package
- The package removes the old wx-config prior before creating the link to
  the real wx24-config, unfortunally it tried to remove wx-config instead
  of wx24-config. wx-config is now used by the new wxGTK (v2.6) package.
Bump the PKGREVISION.

Log message:
Remove the abuse of buildlink that was pkg-config/buildlink3.mk.  That
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables.  Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.

For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.

Log message:
Import old 2.4 branch of wxGTK as wxGTK24, for packages that still need it.
