Normally curl uses cryptographically strong random provided by the selected SSL backend. If compiled without SSL support, a naive built-in function was used instead. Generally this was okay, but it will result in some downsides for non- SSL builds, such as predictable temporary file names. This change ensures that arc4random will be used instead, if available.
