clang-3.3: Address sanitizer library needs id to be changed on install

[dh@…]

Compiling (and linking) using the -fsanitize=address flags leads to an executable with dangling library dependencies. This is because a library has been installed with a bad id

$ otool -L /opt/local/libexec/llvm-3.3/lib/clang/3.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib 
/opt/local/libexec/llvm-3.3/lib/clang/3.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib:
	/opt/local/var/macports/build/_opt_mports_dports_lang_llvm-3.3/clang-3.3/work/trunk/Release+Debug+Asserts/lib/clang/3.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib (compatibility version 0.0.0, current version 0.0.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 833.25.0)
	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)

Manually fixing the id solves the problem

$ sudo install_name_tool -id /opt/local/libexec/llvm-3.3/lib/clang/3.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib /opt/local/libexec/llvm-3.3/lib/clang/3.3/lib/darwin/libclang_rt.asan_osx_dynamic.dylib

So I guess this just needs to be added to the post-destroot ... I'm not sure if this also affects 3.2.

It does.
