I'd appreciate that. It's useful to be able to use the same binary
on all systems. It's convenient for system management, but it's also
nice for checking integrity of the executable. (You don't have 2 or 3
different, legitimate MD5 hashes for /opt/bin/gpg, for example.)

Maybe the default (if no RNG is selected by options) should be to use
the rndlinux driver since it's the most common interface, but allow it
to be overridden with "rng-options" or something.

Yes, I've noticed -- but the infrastructure is there to make it work,
if only people will contribute the right options and they'll enter
the code. It also seems possible to create a "generic" case for DLL
builds where some environment variable(s) will set the compile options.
This doesn't solve the immediate problem of builds failing, but it
does provide a way for people to work around it via mailing list ideas
without having to understand shell scripts, autoconf, etc.

Yes, that's a fair point. I don't worry about it much, myself, because
it provides a useful function. But if it's no longer necessary to
provide that utility, it's more of a hazard.
