Add support for Mac clang compiler

Makefile modified to support the clang compiler under Mac.
This was tested using clang 4 under Mountain Lion, but should
also work fine under Lion and possibly under Snow Leopard.

It requires the 'Xcode 4.x Command Line Tools' to be installed.

No functional change.
