I fixed pbuilder quite some time ago, and "localhost" now resolves
properly.

I don't think so…
that was part of pbuilder 0.230, which is in stretch-backports+.  And I
haven't done many changes since then.

Once thing I noticed last month though, is that the way /etc/hosts is
create is odd and causes a leading \t:

|mattia at warren ~/pbuilder/build/3684584/etc % cat hosts
|	127.0.0.1	localhost localhost.localdomain warren warren.mapreri.org
|
|	::1     ip6-localhost ip6-loopback localhost6 localhost6.localdomain6
|	fe00::0 ip6-localnet
|	ff00::0 ip6-mcastprefix
|	ff02::1 ip6-allnodes
|	ff02::2 ip6-allrouters
|	ff02::3 ip6-allhosts

That's also fixed in git.
Could that be causing issues for glib?  But I don't think that's the
case, since I can build it here with that leading \t… :(

that's indeed a slighly different problem.  I already fixed pbuilder
for that in git, where `hostname -f` resolves back to 127.0.1.1.
