Naming convention for platforms:
<threading-type>_<processor-family and/or operating-system>_<processor or operating-system derivative>_<compiler>(_<board or application type>)

<threading-type> : ST(single treaded) MT(multi-threaded)

Examples:
ST_MSP430_F5438_CCS5_EXP430F5438 : single threaded, processor-family:TI-MSP430, derivative:F5438, compiler: Code Composer Studio 5, board: EXP430F5438
MT_POSIX_GENERIC_GCC : multi threaded, operation-system: POSIX, derivative: GENERIC, compiler:  Gnu C++ Compiler
