Subject: [PATCH] [Untested] Remove odd looking libpng global link flag
 expansion

If explicit link flag handling is required, it *should* be handled by
FindPNG, and we should explicitly bind these kind of things to targets,
rather than expanding the global linker flags

I have no apple setup and can therefore not test this commit
