Pass PLATFORM_FLAGS in build_detect_platform (#8111)

Browse Source 
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.
