(struct stat st_blocks): Change AC_STRUCT_ST_BLOCKS to

a plain AC_CHECK_MEMBERS, we don't want AC_LIBOBJ(fileblocks) which
the former gives.  Remove the commented-out code that was to have
munged fileblocks out of LIBOBJS.  This fixes mingw, where the lack of
st_blocks and absense of the fileblocks.c replacement caused build
failure.  Reported by "The Senator".
(struct stat st_rdev, st_blksize): Combine into a single
AC_CHECK_MEMBERS.
