I followed your suggestions and hence I am able to compile my package using

I hope you chose option 3.

On re-reading that email, I think option 2 is wrong, or at least, it isn’t what 
I meant to write:

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

The main problem with option 2 is that it requires you to give that long 
command on each manual re-configure.  It’s better to code the clang-seeking 
rules into an autoconf macro, if only because you will eventually move on to 
Clang 3.9+.

Passing a relative path to CC seems error prone since it only applies to the current working directory and will fail as soon as any Makefile recurses.
