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.
