Bug#528754: kdelibs do not build without avahi

[root <bugreporter@udmvt.ru>]

Package: kdelibs
Version: 4:3.5.10.dfsg.1-2
Severity: serious
Justification: no longer builds from source

I have found, that it is not possible to turn off some
questionable features, like dnssd.
patch debian/patches/98_buildprep.diff makes ./configure 
fail without libavahi-dev installed.

That is true for Debian/unstable users.
Is that correct, that zeroconf, dnssd, auto-configuration,
auto-publication, auto-discovery, etc. services are now the core of KDE
and not the optional usability improvements (sometimes unneeded),
that opens additional attack vectors (silently)?

If so, why is it true for Debian and not true for upstream?
Still, it is possible (by hand-editing patch files) to compile
debianized kdelibs without extra dependencies on libavahi.

So here is the additional wishlist:
 * fix the ./configure, put back or add new --without- and --disable- options
 * split all the questionable improvements into separate packages
 * make kdelibs Suggest such features or Recommend, but not Depend on them.
