bind-9-packages: RPS and both '--enable-static' and '--disable-static'?

Thanks for giving our packages a shot!

I am not sure if you are aware of it but writing a library implementing
the DNSRPS API is not something entirely straightforward.  See the
"librpz_0_t" type in lib/dns/include/dns/librpz.h for a list of methods
comprising the library interface.  Also note that the only working
implementation whose existence I am aware of is a proprietary one.

Given the above, a strong enough motivation for using --enable-dnsrps in
the packages we build and support is lacking.  Note that Debian and its
derivatives provide tools which make rebuilding a source package with
different compile-time options fairly convenient.

Thank you for catching this, we will fix it.
