RFR: JDK-8139653: Freetype bundled on macosx, but not correctly linked

[Tim Bell]

Erik:

> When building macosx openjdk and enabling bundling of freetype (which is
> usually not the default), the makefiles will copy the library in, but
> libfontmanager will not be able to link to it at runtime. This is caused
> by a peculiarity on macosx where a library that is being linked to
> specifies the rpath to use in any library that links to it. At Oracle we
> currently link to the libfreetype in x11 from Quartz, which is located
> in /opt/X11/lib/libfreetype.6.dylib, so the libfontmanager we build will
> only look in that location at runtime.
>
> This patch adds a new build step, using the install_name_tool which can
> rewrite this rpath to where you actually have a dependency on your
> system. In this case right next to libfontmanager in the same directory.
> I also changed the import logic that copies in libfreetype so that it
> doesn't a .6 at the end on macosx.
>
> This patch does not change the defaults for bundling of freetype, nor
> does it change how Oracle bundles freetype. That may come later.

Looks good to me.
