You should move those two into a subdirectory called "${D}/${includedir}/libpng12/"

That way they will still be available for anyone who needs them.

The .la, .a seen above should be similarly renamed to be libpng12...  The .so 
should be dropped, as anyone who needs the alternative version would need to 
directly specify it.

Should be renamed to be libpng12.pc.

(Note both the .la and .pc files will likely need to be modified to reference 
the correct header and library paths.)

The above should be renamed to be "libpng12-config".

(Again, make sure that the results of it match the renamed .a/.so and include 
paths.)
