Maybe we should merge all of the makefiles for subdirectories of
src/backend into a single makefile.  The major disadvantage would be
that you couldn't rebuild a subdirectory any more by typing make -C
src/backend/executor or whatever.  And I do do that sometimes, so
maybe it would be annoying, but presumably it would make the
dependency issues a lot easier to deal with.

I guess I'm a bit skeptical about the idea of porting to a new build
system.  There's a good chance of replacing the problems we know about
with new problems that are no less serious, but merely unknown to us.
But I'm not going to stand here and hold my breath if everyone else
thinks it's a good idea.
