Bug#992928: libtasn1-6 arch-only FTBFS: Can't exec "gtkdocize": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 293.

Source: libtasn1-6
Version: 4.16.0-2
Severity: serious
Tags: ftbfs

libtasn1-6 fails to perform an arch-only build (but succeeds a full
build). A build ends with:

| dh binary-arch
|    dh_update_autotools_config -a
|    dh_autoreconf -a
| libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, 'build-aux'.
| libtoolize: copying file 'build-aux/ltmain.sh'
| libtoolize: putting macros in AC_CONFIG_MACRO_DIRS, 'm4'.
| libtoolize: copying file 'm4/libtool.m4'
| libtoolize: copying file 'm4/ltoptions.m4'
| libtoolize: copying file 'm4/ltsugar.m4'
| libtoolize: copying file 'm4/ltversion.m4'
| libtoolize: copying file 'm4/lt~obsolete.m4'
| Can't exec "gtkdocize": No such file or directory at /usr/share/autoconf/Autom4te/FileUtils.pm line 293.
| autoreconf: error: gtkdocize failed with exit status: 2
| dh_autoreconf: error: autoreconf -f -i returned exit code 2
| make: *** [debian/rules:48: binary-arch] Error 25
| dpkg-buildpackage: error: debian/rules binary-arch subprocess returned exit status 2

Likely, moving gtk-doc-tools to Build-Depends would fix the issue, but
Andreas Metzler found a way to avoid this for gnutls28.
