Comment 19 for bug 1740517

No need to update 1.2, at least for Vulkan support. If no one is complaining about loadso for 1.2, I think it's safe to leave that alone in Bionic and just be correct going forward into Cosmic. We can always revisit in a separate bug report if something serious arises, but I don't predict that will happen.

There shouldn't be any ABI issues; SDL still exports the same symbols, just some of those functions will return an error code immediately if support has been disabled. Since we need SDL to work with binaries that are shipped for generic "Linux" platforms that can't promise a specific distro or configuration (both for Steam and just delivering games outside of package managers in general), we are _religious_ about keeping a stable ABI in all circumstances for SDL...so it's safe to change those configure options even for LTS.
