Hmm, weird.

sudo pbuilder --build --basetgz /var/cache/pbuilder/base-sid.tgz
ocaml-fdkaac_0.2.0-1.1.dsc

fails here with pbuilder 0.215+nmu3 (+ the binNMU patch) and sudo
1.8.10p3-1+deb8u2

Added some debugging to override_dh_auto_configure:

Within pbuilder execution the following relevant environment variables
are set, well, interestingly:
USERNAME=root
SUDO_USER=beckmann
LOGNAME=pbuilder
USER=root

But all commands return sane values:
$ id
uid=1234(pbuilder) gid=1234(pbuilder) groups=1234(pbuilder)
$ whoami
pbuilder

So the test seems to be broken, since it uses an unreliable environment
variable ($USER) which may have incorrect content first before checking
whoami.

PS: I didn't notice the ./bootstrap script, that does regenerate
configure properly
