[Buildroot] [PATCH] libsndfile: Add -D_FILE_OFFSET_BITS=64 to configuration

[Ryan Mallon]

libsndfile requires sizeof(sf_count_t) == 8, where sf_count_t is a
typedef alias for off_t. This is not true by default for all
tool-chains, which leads to a runtime assert failure in binaries
compiled against libsndfile. See:
    
  http://permalink.gmane.org/gmane.comp.audio.libsndfile.devel/229
   
Add -D_FILE_OFFSET_BITS=64 to the configuration for libsndfile to
ensure that off_t is the correct size.
