Makefile for Makefile.PL perl host packages

Hi guys
I want add a package to host(tools) in openwrt and it is dependence of a target package. The package is libxml-parser-perl-2.44 and dependence is expat 2.2.8. I have already compiled and installed expat2.2.8 in host(staging_dir/host) but have a issue for configure for libxml-parser-perl in make file. In my Ubuntu terminal If I use:

perl Makefile.PL PREFIX=/foo/bar

all things I right but I don't know to to use in make file of openwrt for host package. (/tools/xml-parser) you can see make file in below

include $(TOPDIR)/rules.mk

PKG_NAME:=XML-Parser
PKG_VERSION:=2.44
PKG_MD5SUM:=af4813fe3952362451201ced6fbce379
PKG_RELEASE:=1

PKG_SOURCE:=$(PKG_NAME)-$(PKG_VERSION).tar.gz
PKG_SOURCE_URL:=http://cpan.metacpan.org/authors/id/T/TO/TODDR/

HOST_BUILD_PARALLEL:=1
include $(INCLUDE_DIR)/host-build.mk

define Host/Configure 

        (cd $(HOST_BUILD_DIR)/$(3);
                $(STAGING_DIR_HOST)/bin/perl Makefile.PL \
                PREFIX=$(STAGING_DIR_HOST) \
                EXPATLIBPATH=$(STAGING_DIR_HOST)/lib \
                EXPATINCPATH=$(STAGING_DIR_HOST)/include \
                INSTALLDIRS=site \
                INSTALLSITELIB=$(STAGING_DIR_HOST)/lib/perl \
                INSTALLSITEARCH=$(STAGING_DIR_HOST)/lib/perl; 
        )
endef


define Host/Compile
        +$(MAKE) $(HOST_JOBS) -C $(HOST_BUILD_DIR)
endef

define Host/Install
        $(MAKE) -C $(HOST_BUILD_DIR) install
endef

define Host/Clean

        $(MAKE) -C $(HOST_BUILD_DIR) uninstall
        $(call Host/Clean/Default)
endef

$(eval $(call HostBuild))

I found some package with Make.PL but all of them was target not host and it has different strategy.
Please help me in define Host/Configure part
Thanks

Could that pkg be intended for the tool chain, rather that the target image?
