-    meson: add option to force docbook2x format
+    meson: fix docbook2x detection
     
-    Some distros ship docbook2x as docbook2man, which perplexes the logic in
-    the meson.build that chooses the "docdtd" value.
-    
-    Add a build option to always use the newer docbook2x docdtd value.
+    docbook2man can sometimes be docbook2x and other times be docbook-utils.
+    Rather than compare paths, use version constraints to detect version.
