  scripts: Remove the support for "install" targets from all makefiles
  
  In most of the legacy makefiles (with only a few notable exceptions
  such as makefile.linux), the "install" targets have been broken since
  libpng-1.5.0beta01. Specifically, the "install-shared" targets produced
  incorrect library names, due to a missing symbol in the definition of
  the LIBSOREL macro.
  
  Rather than correcting this long-standing and long-untested error, we
  decided to remove the support for "make install" altogether, from all
  legacy makefiles. Further use of "make install", "make install-static"
  or "make install-shared" will fail with an error message.
  
  Going forward, the only tested and supported manners to install libpng
  shall be the conventional build and install procedures driven by the
  configure script or by the CMake file.
