Bug#677666: pbuilder: using BUILDUSERNAME does not change USER

[Hendrik Tews]

Package: pbuilder
Version: 0.211
Severity: important

Hi,

when I use BUILDUSERNAME=pbuilder, pbuilder changes to user
pbuilder, but does not change the value of USER. This yields a
build failure for packages that check via $USER that they are not
configured as root, for example ocaml-cry (#670733).

When I place id and env into the configure script of ocaml-cry at
line 2870, I see

+ id
uid=56789(pbuilder) gid=56789(pbuilder) groups=56789(pbuilder),1234(pbuilderccache)
+ env
USER=root
SUDO_USER=tews
USERNAME=root

shortly later the configure script fails, because it must not run
as root.
