build-sys: check for gtk-doc by default
This patch add "check|yes|no" concept for --{disable,enable}-gtk-doc configure option. (We use the same concept for many u-l-ng compile options.) The gtk-doc is required for "make dist" (not sure if this is good idea..), so it makes sense to enable gtk-doc by default. Signed-off-by: Karel Zak <kzak@redhat.com>
