Bug#1128912: texinfo: building a second time fails in dh_installdocs with "debuild -i -us -uc -b"

Source: texinfo
Version: 7.2-5
Severity: important

Building texinfo a first time with "debuild -i -us -uc -b" succeeds,
but rebuilding it with the same command fails with the following
error:

[...]
# install all the files
dh_install
make[1]: Leaving directory '/home/vlefevre/tmp/tmp0/texinfo-7.2'
   dh_installdocs
dh_installdocs: error: Cannot find (any matches for) "doc/refcard/txirefcard*.pdf" (tried in ., debian/tmp)

make: *** [debian/rules:27: binary] Error 25
dpkg-buildpackage: error: debian/rules binary subprocess failed with exit status 2
debuild: fatal error at line 1185:
dpkg-buildpackage -us -uc -ui -i -b failed

Both unstable (7.2-5) and experimental (7.2.92-1) give this error.
