This commit fixes various build failures caused by the host-perl
series.
Currently, the variables PERL and PERL5LIB are available only during
the configure step of host-intltool, but they are also needed when
running host-intltool, in all packages that depend on
host-intltool. Without them, host-intltool cannot work as it doesn't
find the libxml-parser-perl module installed in
$(HOST_DIR)/usr/lib/perl.
This commit therefore makes the PERL and PERL5LIB variables global, so
that all packages can access them.
