CoEVP and LULESH do not link on OS X

[mcpherson]

Compilation of CoEVP library succeeds but static library generation (ar) gives errors on OS X of this form:

...
ar: warning: MathUtilitiesSpecial.o truncated to MathUtilitiesSp
ar: warning: MemoryUtilities.o truncated to MemoryUtilities
ar: warning: ParallelBuffer.o truncated to ParallelBuffer.
ar: warning: AbstractStream.o truncated to AbstractStream.
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libcm.a(ApproxNearestNe) has no symbols
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: file: libcm.a(TimeRecorder.o) has no symbols
...

Then when attempting to link into LULESH, we see errors of this form:

Undefined symbols for architecture x86_64:
  "_freeReplyObject", referenced from:
      SingletonDB::push(unsigned __int128 const&, std::__1::vector<double, std::__1::allocator<double> > const&, unsigned long) in libcm.a(SingletonDB.o)

clang: error: linker command failed with exit code 1 (use -v to see invocation)

This is all likely compatibility issues between g++ and clang. I don't know if it's worth the effort tho chase this down.

On 10.11.3 I see the same static library generation warnings, however LULESH links and executes correctly.
