Bug#873041: libxcursor1-udeb: Broken dpkg-shlibdeps rule

[Jeremy Bicha <jbicha@ubuntu.com>]

Package: libxcursor1-udeb
Version: 1:1.1.14-2
Severity: serious
X-Debbugs-CC: debian-boot@lists.debian.org

When libxcursor was converted to dh's rules, the line defining PACKAGE
was accidentally removed.

So this line:
dh_makeshlibs -V "libxcursor1 (>> 1.1.2)" --add-udeb=$(PACKAGE)-udeb

gets interpreted as:
dh_makeshlibs -V "libxcursor1 (>> 1.1.2)" --add-udeb=-udeb

Which leads to packages like gtk+3.0 failing to build from source:

=========
dpkg-shlibdeps: warning: can't parse dependency -udeb (>> 1.1.2)
dpkg-shlibdeps: error: invalid dependency got generated:
