Indeed, apart from moving those parts of Makefile.in building libgnat and
tools to a separate file/directory at the toplevel: this would massively
untangle the build procedure.
One issue I found problematic when looking at what needs to be done to
avoid those recursive makes was the need for a special .c.o rule in
Makefile.in with ALL_ADA_CFLAGS added to the basic compilation flags. If
this part is to be moved to Make-lang.in, this cannot be handled by a
suffix rule which wouldn't be specific to the ada compilations. Unless
there's some special make magic, you have to provide a command with every
ada .c file which includes those flags.
