lang/rust builds with gcc 4.9, so it sidesteps clang.

I have the base clang installed in addition to gcc:
/usr/bin/clang, /usr/bin/clang++
(I'm reluctant to publicly post instructions how to set this up,
since I know people who don't understand what they are doing will
mess with it and shoot themselves in the foot.)
Beyond that, I have the following ports infrastructure patches:
* Link clang,clang++ as cc,c++ into the leading PATH directory.
* Move amd64 from GCC4_ARCHS to CLANG_ARCHS.
* In the clang module, also link /usr/local/bin/clang and clang++
into the leading PATH directory.
Ports that use MODCLANG still use the ports clang with this.
If I didn't miss something, base clang++ uses libc++ and ports
clang++ still uses libestdc++.
