GHS: Place build system outputs per target output directives

-- Set output and object file locations
-- Suffixes are no longer being forced but will now follow the target properties
   By default GHS tools have no suffix for executable files so
   CMAKE_EXECUTABLE_SUFFIX was changed to meet this behavior
-- Remove #if 0 blocked out code; it has been replaced.
   Forcing the -relprog option has been removed from non-kernel executable targets.
   The default value of this option (if it is even available) is determined by the
   tool-chain for the specified target and platform (Some tool-chains default to
   -locatedprogram).  The use of -relprog can have unexpected results as it cannot
   always produce a fully relocated executable.
-- Clarify use of CMAKE_BUILD_TYPE to control build configuration
