Solaris/PPC design decisions

• Port Endianness
   The decision was to make the port MSB despite the fact that the original (circa Solaris 2.5.1) port was LSB.

• Names
   There are number of names used to identify platform architecture,
   cpu architecture, etc. Solaris source tree uses these names extensively and
   Solaris itself. Agreed choices are

• Predefined C Preprocessor symbols

    ~_\//powerpc and \//\//powerpc64
    \//\//powerpc\//\// and \//\//powerpc64\//\//  /\* for GNU compatibility \*/
    \//\//ppc and \//~_ppc64              /\* for shortcuts \*/

All the *64 symbols are defined only when compiling for 64 bit environment
