How to enable coverage option in the latest drop of clang/llvm

[Sinha, Prokash]

Hi All,

Initially I was having problem compiling clang/llvm, then found some of the compilation error.

Now I can build it on freebsd 10.

But I need to have the coverage option on.  On Mac it is still there -

bash$ clang --coverage main.c  -###
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin12.5.0
