Rodrigo Rebello 770965edfc sdl_mixer: add patch to fix SDL_mixer.pc for static linking
A 'Libs.private' field needs to be present and properly defined in the
pkg-config file in order for static linking against SDL_mixer to work.

Besides adding the mentioned field, the included patch also modifies
configure.in so that EXTRA_LDFLAGS (which is now also used as the value
of 'Libs.private') no longer includes SDL_LIBS. This is done so as to
prevent libraries required by SDL from being listed twice when
'pkg-config --libs --static SDL_mixer' is run (they're already shown
because of the 'Requires: sdl' line in SDL_mixer.pc). Makefile.in is
adjusted accordingly as well.

Also enable autoreconf for this package since we're patching
configure.in.

Subject: [PATCH 1/1] Add 'Libs.private' field to pkg-config file
In order to support static linking, SDL_mixer.pc should include a
'Libs.private' field listing all the libraries that SDL_mixer requires.
This patch adds such a field and also modifies configure.in so that
EXTRA_LDFLAGS (which is now also used as the value of 'Libs.private')
no longer includes SDL_LIBS. This is done so as to prevent libraries
required by SDL from being listed twice when 'pkg-config --libs --static
SDL_mixer' is run (they're already shown because of the 'Requires: sdl'
line in SDL_mixer.pc). Makefile.in is also adjusted accordingly.
