-- Do not use CMAKE_C_FLAGS_RELEASE flags when CMAKE_BUILD_TYPE is empty
   if CMAKE_BUILD_TYPE was not set the generator would use Release settings
   this does not match the documented behavior of CMAKE_BUILD_TYPE

-- CMAKE_C_FLAGS_<CONFIG> not used when -kernel is present
   Fixes issue where CMAKE_C_FLAGS_<CONFIG> is ignored when -kernel option is present as a compiler option
   When the -kernel option is added to an executable it uses a different set of language flags
   This does not occur -kernel=<type> is used or if it is added as part of a link flag
   The variables CMAKE_<LANG>_GHS_KERNEL_FLAGS_<CONFIG> are removed
   NOTE: By default this only added the flag -ldebug which links in the debugger library.

-- Separate compiler options by newlines
