 What architectures are in your versions of:

 {{{
 /opt/local/libexec/llvm-3.8/lib/clang/3.8.0/lib/darwin/libclang_rt.10.4.a
 /opt/local/libexec/llvm-3.8/lib/clang/3.8.0/lib/darwin/libclang_rt.asan_osx_dynamic.dylib
 /opt/local/libexec/llvm-3.8/lib/clang/3.8.0/lib/darwin/libclang_rt.cc_kext.a

 }}}

 Those need to be fat.  The suggested changes don't address that problem.
 I'm glad that your restricted test cases work fine, but it won't be
 realistically useful until https://llvm.org/bugs/show_bug.cgi?id=25885 is
 addressed.

 I am quite aware of the problem.  I'm not expecting to force an entire fat
 toolchain on the users.  The toolchain should be the architecture that
 they're building MacPorts for (ie, CHOST in automake language), the
 runtime libraries should be the architecture that the toolchain can target
 (ie: CTARGET in automake language).
