[PATCH] Support SPARSE in Makefile, better SPARSE_FLAGS

[Pavel Roskin <proski@gnu.org>]

Support SPARSE in Makefile, better SPARSE_FLAGS

This patch makes it possible to use some other program instead of sparse
(e.g. a wrapper around sparse).  It also provides a better default for
SPARSE_FLAGS.  __BIG_ENDIAN__ should not be needed.
