[svn-r23610] Improvement: DFFV-8245
Use Clang as the compiler for the Mac platform. Changed all Mac to use clang/clang++ as the default C and CXX compilers if not provided by the user. Still use gfortran as the default fortran compiler since Apple does not provide any fortran compiler. HDFFV-8245: bug fix. Snow Leopard (darwin 10.X) does not have clang++. Reversed it to use gcc/g++ as the default C and CXX compilers for Darwin 10.X systems. Tested: h5committest plus duck (darwin 11), wren (darwin 12) and fred (darwin 10).
