rng-tools PKCS#11 and rtlsdr

Hi all, am currently updating the rng-tools and there are some new compile options needed to compile it.

--without-pkcs11 Disable pkcs11 support. --without-rtlsdr Disable rtlsdr support.

so a question arises for me, should we enable Smartcards --> https://github.com/OpenSC/OpenSC/wiki and also DVB dongles as entropy resources --> https://github.com/librtlsdr/librtlsdr for the rng-tools --> https://github.com/nhorman/rng-tools/releases in IPFire, whereby two new libs are needed ?

Best,

Erik
