  build: Update scripts/makefile.*
  
  Apply the following updates:
   * Tidy up the compiler flag definitions.
   * Update the Darwin, Linux and MSYS makefiles to match the compiler
     flags used in scripts/makefile.clang and scripts/makefile.gcc.
   * Add the `pngtest-static` target in the Darwin makefile, following
     on the Linux makefile.
   * Rewrite some of the implicit make rules to match one another more
     consistently.
   * Make corrections in the copyright years to match git log.
