* util/misc.c: Include config.h.
        [!HAVE_MEMALIGN]: Do not include malloc.h.
        (grub_memalign): Use posix_memalign, if present. Then, use
        memalign, if present. Otherwise, emit an error.

        * util/grub-emu.c: Do not include malloc.h.

        * include/grub/util/misc.h: Include unistd.h. This is required for
        FreeBSD, because off_t is defined in unistd.h. Reported by Harley
        D. Eades III <hde@foobar-qux.org>.

        * configure.ac (AC_GNU_SOURCE): Added.
        (AC_CHECK_FUNCS): Check posix_memalign and memalign for the host
        type.
