Subject: Add a configure setting to skip "doc/"

This should fix all remaining build issues with documentation
generation. Finally.

The new "--disable-docs" option should be used to skip documentation
completely, whereas "--without-asciidoc" can be used if both manual and
man page should not be rebuilt. As a consequence, "--without-asciidoc"
can only be combined with "--enable-docs" if ready-made documentation
already exists in "doc/". This is true for release tarballs (where we
include prebuilt documentation for the sake of portability and
simplicity), as well as for Git checkouts where the documentation has
already been built earlier.
