The variable ACLOCAL_DIR points to the staging area but is not useful
anymore because the target package was removed. Fix ACLOCAL_DIR by
pointing to $(HOST_DIR)/usr/share/aclocal and remove ACLOCAL_HOST_DIR
because ACLOCAL_DIR has the same value so it's not useful anymore.
Also remove the reference to ACLOCAL_HOST_DIR from the host-autoconf
package.
