Maybe the bind configure could be called in a post configure hook.
This way, bind would be configured in the configure step too.

For at least one external toolchain, the bind configure can't find the
target compiler because it is expecting arm-buildroot-linux-gnueabi-gcc
while the binary name is arm-none-linux-gnueabi-gcc.
Maybe setting CC here would fix this.

If a hook is used, TARGET_CONFIGURE_OPTS can provide most of variables needed,
fixing the issue with some external toolchains.
Something like this:
DHCP_BIND_CONF_ENV = \
	$(TARGET_CONFIGURE_OPTS) \
	GNU_TARGET_NAME=$(GNU_TARGET_NAME) \
	GNU_HOST_NAME=$(GNU_HOST_NAME) \
	BUILD_CC="$(HOSTCC)"

define DHCP_CONFIGURE_BIND
	$(DHCP_BIND_CONF_ENV) $(DHCP_MAKE) -C $(@D)/bind bind1
endef
DHCP_POST_CONFIGURE_HOOKS += DHCP_CONFIGURE_BIND

What do you think about this?
