dh-perl6 vs. dh-raku: reproducibility issues with vendor/precompiled

[Mattia Rizzolo]

(just dumping a quick point else I'm sure I'll forget by the time I get to
this mail when on the computer..)

A build process really must not create random files in HOME, and possibly
not even try to access them...

If having a nonexistent home dir (which... Isn't the case of boh default
pbuilder and sbuild?) leads to an ftbfs, that's pretty much a RC bug.
Although I don't remember the reference by heart, I'm quite sure I've seen
such RC bugs filed in the past.
