Bug#969740: tabble FTCBFS: broken embedded copy of AM_PATH_GTK_2_0

[Helmut Grohne <helmut@subdivi.de>]

Source: tabble
Version: 0.43-3
Severity: important
Tags: upstream fixed-upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

tabble fails to cross build from source, because it ships a broken,
outdated, embedded copy of AM_PATH_GTK_2_0 in aclocal.m4. Please remove
this embedded copy and use the packaged one instead. Failing that,
please update the copy and register it with the security tracker. Please
refer to https://wiki.debian.org/EmbeddedCopies for more details on the
process. This bug report comes without a patch, because the actual
problem has long been fixed. tabble just happens to ship a copy of the
bug.
