Makefile support for separate debug and release build targets

I think GNU Coding Standards call for an install-strip to install the non-debug version ?

I think the binary targets should be phony too. The current SOURCES is broken because it's missing two submodules (and also the manifest), and cargo build already knows what to do.

That doesn't work directly because:

• by default, Rust keeps debug info in debug builds and strips it in release ones
• this can be overridden in the manifest (e.g. [profile.release] strip = "none" in Cargo.toml) or in other like environment variables
• thus, whether an artifact has debug info is a property of how the artifact was built, not of how it is installed

Of course, you can enable debug info in [profile.release] and then strip it in make install-strip. But it will slow down the builds in this case.

Isn't install -s as effective ?

Just as effective as strip, yes, but a bit slower than letting Cargo do it.
