+TODO: Check that the part removing the dependency from stamp-gnatlib1
+to stamp-gnatlib2 is not necessary anymore with gcc-9.
+
+* Link tools dynamically.
+* Prevent direct embedding of libada objects:
+ Mark ALI files as read-only, remove objects after the build.
+ A solution keeping the objects would be more intrusive.
+* Rebuild gnatbind/make/link with themselves.
+ This removes unneeded objects inherited from the hardcoded bootstrap list.
+ The same thing would be useful for gnat1drv, but is less easy.
+* TOOLS_ALREADY_COMPILED lists LIBGNAT objects that
+ gcc/ada/gcc-interface/Makefile should not rebuild.
+* Link libgnat/gnarl with LDFLAGS.
+* Link libgnarl with an explicit path to a shared object.
+ This prevents undefined symbols or unwanted usage of host libgnat.
+* Compile with -gnatn for efficiency.
+ Double-check the link since Debian moves some symbols.
+* set LD_LIBRARY_PATH so that rebuilt tools can be executed.
