aghermann FTBFS and fakeroot

[Gabriele Giacone <1o5g4r8o@gmail.com>]

Hello,
I reproduced aghermann FTBFS and fixed it by switching fakeroot from
-tcp (I guess the active one on ironforge, at least active 6 days ago
when aghermann FTBFS'ed) to -hurd.

mbanck made me notice it could be useful making buildlogs say which
fakeroot buildd/manual builds used. Attached patch does the job.
