Updated base requirement on GNAT version and the fact that stage1 of the bootstrap now uses the base compiler's libgnat allows for more Ada features in the runtime and makes these pragma obsolete.
Added comments in files that are still built during stage1 and that need
to be modified with care now that there is no pragma to prevent
incorrect modification.
Tested on x86_64-pc-linux-gnu, committed on trunk
