usage: cgsystem [[-][enable-]64[bit]] [[-]cur[rent]] [[-]conf[igure]]
Returns an identifier for the type of system. If the -cur[rent] option
is specified, then reads the system name from the make.system file, if
it exists. If the -64[bit] flag is set, checks if 64-bit is supported
and if so, returns a version of the system name ending with 64. The
-con[figure] flag, will update the make.system file with the system name.
