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.
