mtd-utils: Use AC_SYS_LARGEFILE
Currently mtd-utils on 32bit systems fail on devices >2GiB due to off_t being a signed 32bit type. Add AC_SYS_LARGEFILE to make off_t a 64bit type. Adding AC_SYS_LARGEFILE results in _FILE_OFFSET_BITS being defined to 64 in include/config.h. To let this have an effect we must make sure that include/config.h is included before all other includes which is archieved by adding its inclusion to CPPFLAGS.
