- Turns out the variable wasn't being set, and thus the flags weren't being passed
- Passing the flags via those variables is basically a bad idea, and it
turns out to break libpng's config script
- The flags need to be passed during link as well, otherwise the binary
isn't linked as a fat one
Besides the immediate performance improvement, reducing
the frequency of downloads should make spurious
failures (network, rate-limiting...) less bothersome.
