Of course not.  The problem is just that we specify, via environment,
a path to a non-existent python executable.

I think it works as designed, but it was not designed especially for
wget and its test suite.  I think it would be fine to simply print
a warning, instead of bailing out, but I'm not sure it's possible to
tweak that in a clean manner, and IIUC that would be a job for next
automake releases, not for wget.

Same thing here I guess.
