Howdy,

I'm incorporating FreeImage into an automatic build system and needed to update Makefile.osx for newer versions of Xcode/OSX:

Changes:

  1. settable SDK and min SDK
  2. SDK developer path set using xcode-select, so the Makefile will work with both newer and older versions of Xcode
  3. removed ppc build
