For now Debian, Fedora, RHEL, etc. build BIND with 'native PKCS11'
support. Till recently, that was the strict requirement of DNSSEC.
The problem is that this restricts cross-platform features of FreeIPA.
With the help of libp11, which provides `pkcs11` engine plugin for
the OpenSSL library for accessing PKCS11 modules in a semi-
transparent way, FreeIPA could utilize OpenSSL version of BIND.
BIND in turn provides ability to specify the OpenSSL engine on the
command line of `named` and all the BIND `dnssec-*` tools by using
the `-E engine_name`.
