Improved stack handling for os9 target in lwlink Added "stack" as a valid symbol in the __os9 section. All instances of __os9 are now polled for "stack" symobls and the values added to the stack size set in the linker script. The stack size is then added to the final data size of the module. Also set a default minimum stack size of 32 bytes.
