Subject: [PATCH] Add configure option to disable man pages

Building the man page requires asciidoc, if building from the source
repository. Add option to only install the program, but not the man.

When building from the release tarball, the man page is already built.
So we can still default to installing it, and requiring asciidoc/a2x.

Closes #264
