This is unlikely a bug in sbuild, sbuild is just a perl script which
retrieves the Debian source, unpacks it, enters the package toplevel
directory and executes dpkg-buildpackage.

(In fact, the package fails to build as well when I build it using
dpkg-buildpackage alone, without sbuild).

I believe it is a genuine gettext bug, which is triggered by the
default environment variables set by dpkg-buildpackage (CFLAGS et al),
and/or the default way by which ./configure is called
(which is determined by debhelper).

How can I debug this? Let's suppose that I have already
ran ./configure and make to build the package. How do I execute
a single test? (not the full make check).

Thanks.
