Add option to use Ada code in ramstage
If selected, libgnat will be linked into ramstage. And, to support Ada package intializations, we have to call ramstage_adainit().

+ * package level initialization (e.g. you can initialize huge arrays in
+ * a loop instead of cluttering the binary).
+ *
+ * When an Ada main() is in charge, GNAT emmits the call to the initia-
+ * lizations automatically. When not, we have to call it explicitly.
