Just a quick guess, without having tested it:

I'm not sure why you have to put the "echo" commands into separate
parentheses. AFAIR that isn't necessary, and indeed an overquoting.
So I propose to replace this:

... with that:

----------------------------------------------------------------------------
PKG_CHECK_MODULES([SDL_MIXER],
    [SDL_mixer],
    ,
    [
      echo "SDL_MIXER not found via pkg_config, checking with AC_CHECK_LIB:"
      AC_CHECK_LIB([SDL_mixer],
         [Mix_OpenAudio],
         ,
         [AC_MSG_ERROR([SDL_mixer not found!
http://www.libsdl.org/projects/SDL_mixer])]
      )
      echo "SDL_MIXER successfully located"
    ]
)
----------------------------------------------------------------------------

Does that solve the issue?
