Allow absolute path again #18

This means we can include files from OUT_DIR which is useful for dynamic file generation (I need to merge several folders into one place). Using relative path is simply not enough here.

Can I ask why absolute paths are not allowed?

IIRC it breaks incremental builds, for example, if you have a bunch of C headers in absolute path, and you decided to update the headers, then incremental build won't take that as a change (otherwise they will have to do an exhaustive search for all possible files referenced). You can only rebuild everything from scratch which is not economical given that Rust is still having a slow compile time.

Interesting. Thanks for the explanation, @stevefan1999-personal.
