Supporting cross-compilation of xdg-utils opens the way to trying 
cross-compilation of Qt things.

Things like XS are unsupported -- going by 
https://arsv.github.io/perl-cross/modules.html and the web page that 
states that external modules need to be copied into Perl first (but 
which I cannot find anymore), it sounds rather complicated.
