There is probably a reasonably large thread here which I won't start,
regarding performance implications between 32bit and 64bit binaries.

However, the main driver behind this work is that currently we produce
two entire datasets depending upon whether a customer wants 32bit and
64bit, and it is much simpler for us to produce just one which
supports both, as well as simplifying things for customers.

Solaris comes with native support for this, with the main OS providing
32+64bit libraries and 32bit binaries by default with a set of 64bit
optional binaries, so we are merely extending this support in pkgsrc
for users who will already expect it to exist.
