binutils: Add gnu-config-native to DEPENDS

do_configure() in binutils.inc includes an explicit call to
gnu-configize so we need to make sure that gnu-config-native is
present.  Previously this was being dragged in with the rest of the
autotools stuff, but commit 54a3e2ee37003fc56af0339f857b0b6442790c26
disabled that for binutils-cross on the grounds that "we don't
autoreconf" the toolchain components.  Fix this by adding
gnu-config-native itself explicitly to DEPENDS.
