Dear Francois Perrad,

Thanks a lot for working on this. Definitely a lot better than the
previous solution from Bernd that required tons of host Perl packages
to be added. A few comments below.

So, if there's no issue, why do you mention this?

considere -> consider

Also, I think this should probably be mentioned in the Config.in help
text.

I -> not good to use such formulation. What about:

"The cross-compilation case is not supported, a host executable gets
built. For this reason, this step is disabled."

Also, since you're fixing several independent problems, what about
doing a single patch for each problem ?

Do you think you could write the patches in a way that makes them
potentially acceptable upstream ?

Do we really need a compile time option for this? Can't this be
configured at run-time in some configuration file?

Shouldn't the default be an empty string rather than the "the
administrator of that BR system" ?

Lines too long I believe, please wrap at 72 characters.

Thanks!
