MakeFile adjustments to build on OS X 10.10.5

[jeremydouglass]

In order to build FIAT on OS X 10.10.5 I was unable to use the default MakeFile -- make errors out with:

ld: library not found for -lopencv_gpu

I needed to make adjustments to the Makefile line 17, removing these arguments:

• -lopencv_gpu
• -lopencv_legacy
• -lopencv_ocl
• -lopencv_ts

After that FIAT built with no apparent issues.

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.0.0 (clang-700.0.72)
Target: x86_64-apple-darwin14.5.0

I also had to add the --std=c++11 flag to the compiler lines in the Makefile to get round issues with Protobuf compatibility on my Mac. Errors included below to help future searchers :)
