Ok - Here's what we have in config.log...

  $ ./configure --prefix=/opt/pkg --build=x86_64-apple-darwin16 
--host=x86_64-apple-darwin16 --mandir=/opt/pkg/man

If I create a similar mini-program and compile it with "cc -O2 
-L/opt/pkg/lib" it seems to compile without any problem!

Also here's this...

  $ clang --version
  Apple LLVM version 8.0.0 (clang-800.0.42.1)

Thanks for looking!
