Tweak build system to allow out-of-tree projects.
It's very annoying to have to build libmaple projects in-tree. Users
are just copying the repository everywhere. That's stupid. So I made this:
https://github.com/mbolivar/example-libmaple-project
It needs these patches to work.
Add a header and footer for rules.mk files, so we can change them
around and things will continue to work for the users, who just
include them.
In Makefile, add USER_MODULES to LIBMAPLE_MODULES if it's
nonempty. This is the hook you use to get your code compiled and
linked correctly.
Hack build-targets.mk for stupid reasons I hope to fix later. For now,
you'll need an empty main.cpp in BOTH the libmaple directory and your
directory if you want things to work the way you'd expect.
