[PATCH 2/2] gnu: Add manaplus.

I don't know if there is a better workaround for the SDL headers, but
this problem is rather common: there is a workaround in 'abbaye' and a
special patch for 'pingus'.

The problem is: the source code has lines like this:

  #include <SDL_mixer.h>

but the headers of all SDL packages are placed in “include/SDL/”
subdirectories.  And an upstream often doesn't use "pkg-config" for
every SDL package to define CFLAGS and assumes that all SDL headers are
placed in one directory.  So we have to invent workarounds for such
packages.

I just mention this problem here, perhaps someone will come up with a
general solution.
