I don’t know that syntax, and due to its form, I’ve failed to Google up a 
reference to it, so I don’t know what exactly it is you’re trying to accomplish.

However, I don’t see what’s wrong with either:

1. CC=../../llvm-arm-toolchain-ship/3.8/bin/clang

2. autoconf CC=../../llvm-arm-toolchain-ship/3.8/bin/clang

3. Writing an autoconf macro that seeks out the nearest Clang installation 
compatible with your necessary build flags (-march=armwhatever, etc.).

That’s in increasing order of preference.
