Must set extra_c(xx)flags before including subdir Makefile.local's,
so that there is a blank slate that the subdirs can add on to.
Must include subdir Makefile.local's before global one, otherwise
the compat sources are not added to the list of those to be
compiled.

It makes sense to me to have the little tests for functionality right
next to the comptability implementations of that same functionality.
But also, this means I can now tab-complete ./configure from the three
initial characters (rather than the seven required previously).
We add a magic line to the beginning of each Makefile.local file to
help the editor know that it should use makefile mode for editing the
file, (even though the filename isn't exactly "Makefile").

emacs/Makefile.local to each instance of Makefile.local.
We were previously maintaining two lists of the child Makefile
fragments---one for the includes and another for the dependencies. So,
of course, they drifted and the dependency list wasn't up to date.
We fix this by adding a single subdirs variable, and then using GNU
Makefile substitution to generate both the include and the dependency
lists.
Some side effect of this change caused the '=' assignment of the dir
variable to not work anymore. I'm not sure why that is, but using ':='
makes sense here and fixes the problem.
Some compilers complain that result might be used uninitialized in
this function. I believe such compilers simply aren't looking hard
enough, but it's easy enough to silence them.
