Hello,

libtasn1 4.12 FTBFS against gtk-doc-tools 1.26.
...
Making all in reference
make[5]: Entering directory '/build/1st/libtasn1-6-4.12/doc/reference'

/bin/bash: gtkdoc-mktmpl: command not found
Makefile:1240: recipe for target 'tmpl-build.stamp' failed
make[5]: *** [tmpl-build.stamp] Error 127

Find attached a patch against git HEAD to fix this. If you are not happy
with the requirement for gtk-doc-tools 1.25 I can repost without the
version.xml removal.

Please note that gtk-doc-tools 1.26 is slightly broken, it will throw a
hard error if glib-2.0.pc is not available.

Subject: [PATCH] Update gtk-doc-tools, gtkdoc-mktmpl was removed

Update gtk-doc.make, m4/gtk-doc.m4 and doc/reference/Makefile.am from
gtk-doc git head (that is 1.26 + c08cc78562c59082fc83b55b58747177510b7a70).

Use gtkdocentities.ent instead of generating version.xml by ./configure.
This was introdiced in gtk-doc-tools 1.25, bump ./configure-check.
