luksmeta-v9 generates man pages at build if a2x is available since:

Generate manual page from source during build time
If a2x (asciidoc) is not available during configure time,
a warning will be generated and the manual page wont be
generated nor installed.
Man pages are not needed on target and the build step fails in certain
setups, so disable it.
