Check that library/profiler_builtins actually found some source files

Browse Source 
The current `build.rs` will automatically skip source files that don't exist.
An unfortunate side-effect is that if _no_ files could be found (e.g. because
the directory was wrong), the build fails with a mysterious linker error.

We can reduce the awkwardness of this by explicitly checking that at least one
source file was found.
