Enable installation without --enable-man

Add a pre-generated man page and do not regenerate the man page by
default.

Check the prerequisites to regenerate the man page during configuration
instead of reporting an error later during the build process, and remove
the pre-generated man page after checking, so that --enable-man will
regenerate the man page no matter what.
