Can some hurd people check and explain me why hurd-i386 libs export
private symbols ?

Because IIRC (but I didn't check), the various "_pango*" are marked as
"hidden" with gcc's visibility attribute (same goes for the "_hb_*" and
"_HB_*" symbols).

This difference is undesirable and complicates somewhat the work of
maintainers who will have to deal with arch-specific differences when
there shouldn't be any.
