Flag soup is terrible for dependency management. It only works for a single compiler (family), there's no semantics of what each flag might mean, undefined ordering or grouping of flags like `-ffast-math` or `-fno-fast-math` (which are ABI-affecting) means you don't know what you'll actually get. More fun, if you have multiple prefixes of dependencies, one `-L` can change what any following `-l` flag means (and is primarily why I think that absolute paths to libraries is far better on the link line).
