Without having tested that - this seems to come from

-	export PERL5LIB="${PERL_ARCHLIB}"

which is, when do not causing above build failure, kind-of bug-using :)

Always prepending ${PERL_ARCHLIB} causes for cross-building the attempt
of loading sdk-modules, which is evil.

I'll try to have a detailed look later today or tomorrow.
