Writing a dynamic library in Crystal, and calling it from C

• Download all files.
• Build the Crystal part:

crystal build --release --cross-compile --prelude ./no_main library.cr
              ^ You can leave this out
                        ^ We want to link ourselves!
 ^ Use our custom prelude!
