Summary: At least under MacOS, some things were excluded from the build (like Snappy) because the compilation flags were not passed in correctly. This PR does a few things: - Passes the EXTRA_CXX/LDFLAGS into build_detect_platform. This means that if some tool (like TBB for example) is not installed in a standard place, it could still be detected by build_detect_platform. In this case, the developer would invoke: "EXTRA_CXXFLAGS=<path to TBB include> EXTRA_LDFLAGS=<path to TBB library> make", and the build script would find the tools in the extra location. - Changes the compilation tests to use PLATFORM_CXXFLAGS. This change causes the EXTRA_FLAGS passed in to the script to be included in the compilation check. Additionally, flags set by the script itself (like --std=c++11) will be used during the checks. Validated that the make_platform.mk file generated on Linux does not change with this change. On my MacOS machine, the SNAPPY libraries are now available (they were not before as they required --std=c++11 to build). I also verified that I can build against TBB installed on my Mac by passing in the EXTRA CXX and LD FLAGS to the location in which TBB is installed.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
