With the switch to gradle, we no longer build fat binaries on Mac for any of the native libraries built by gradle. We also no longer run "lipo" to strip out the 32-bit library. Since the media binaries are built using their own Makefile, the native media libraries are still being built with both 32 and 64-bit binaries.

fxplugins.dylib (for architecture i386): Mach-O dynamically linked shared library i386
libglib-2.0.dylib (for architecture i386): Mach-O dynamically linked shared library i386
libgstplugins-lite.dylib (for architecture i386): Mach-O dynamically linked shared library i386
libgstreamer-lite.dylib (for architecture i386): Mach-O dynamically linked shared library i386
libjfxmedia.dylib (for architecture i386): Mach-O dynamically linked shared library i386

This needs to be fixed prior to shipping FX 8, since the binaries are needlessly twice as big as they should be.
