Bug#389670: libsdl-gfx1.2-dev contains symbolic link for libsdl-gfx1.2-4

[Jason Fergus]

Package: libsdl-gfx1.2-dev
Version: 2.0.13-2

It seems that libsdl-gfx1.2-dev contains the symbolic link for
libSDL_gfx.so which points to a file within libsdl-gfx1.2-4.  This
wouldn't be a problem of course except for software which is linked to
look for libSDL_gfx.so instead of libSDL_gfx.so.4 or
libSDL_gfx.so.4.9.0, which is what libSDL_gfx.so from the -dev package
points to.

Anyone who compiles something, then removes the -dev package is not
going to be able to run the program.
