The question from Arne was not about the host variant of
libxml-parser-perl, but about he target variant.

Right, but Arne seems to indicate that when you build a *target* Perl
modules with cross-compiled C code (i.e not a pure Perl module), there
is an ABI compatibility issue, because the host perl and the target
perl don't use the same ABI.

Arne: can you give a specific Buildroot configuration and commands to
test that exhibit the problem?

Thanks!
