Attempt to idiot-proof making and refreshing docs

I mess this up more often than not, and maybe this will do the trick. Remove
the --enable-asciidoc option as it has been superseded by the --disable-doc
option in usefulness. If you want to skip building docs, you skip building
all docs which is much easier when it comes to ensuring the make 'dist' and
'distcheck' targets will always build the manpages and always build the most
up to date manpages.

Developers shouldn't be affected in their normal builds, nor should end
users of the source tarball.
