The 'install-man' target will use your check-executable-or-error-out
stuff, but the main 'install' target will call just 'try-install-man',
that will not stop the build if there are missing tools to generate the
man pages.

Installing just xmlto makes it ask just for asciidoc, install both and it
generates the man pages, please try to check if it works for you so that I can
have your Tested-by.
