build: Correction of OSX Security Framework detection
When a non-Apple compiler is used (e.g., gcc-4.8 from macports), OSX
Security Framework cannot be used, but security framework detection was
not failing. This commit makes security framework optional on OSX
platform, waf will present warning and `*-osx.*` files will not be
compiled in such cases.
Note that on OSX 10.9 even with this fix, compilation with gcc-4.8 will
still fail, because of STL library incompatibility (e.g., boost and
cryptopp libraries usually compiled against Apple-provided STL and
gcc-4.8 uses by default gcc's STL).
