+Manually tell the compiler that strlcpy exists. The `try-build` function seems
+somewhat broken, i.e. any code that I try to pass to it doesn't link because of an
+"undefined reference to main" error (and some more quoting issues with newlines being
+swalloed).
+
+Because both musl and glibc seemt o support strlcpy nowadays, I decided to just skip the
+possibly broken feature-check and hardcode that it exists.
