 libcxx: fixes for Leopard

 1. disable ppc builds. These have never worked so
 far other than very controlled, hand-modified setups.

 Attempts to build libcxx on PPC inevitably failed and
 resulted in tickets, so just disable it fully.

 2. on Intel, esp for Leopard, force universal archs of i386/x86_64.
 These are the only archs that can build libcxx on
 Leopard. We could disable universal completely
 but libcxx builds well enough as i386/x86_64 and I know
 there are users who are using libcxx on 64 bit leopard.

 If one day we do enable libcxx to build on PPC, these
 can be readdressed at that time.
