Reviewers: jat, fabiomfv, Description: Update the mac xpcom plugin for Gecko 2.0 (FF4). This is a platform switch for mac: ppc+i386 to i386+x86_64 to mirror Firefox's platform shift.
Also, fixup the linux libxul linkage: we had been getting lucky with -rdynamic on linux for the JS symbols which can actually be found in libxul (and are required for the mac build).
