more stack frames can be viewed on the same terminal).

`eval-system` option overrides just the value of `builtins.currentSystem`.
This is more useful than overriding `system` since you can build these
derivations on remote builders which can work on the given system.

I wrote the `configure.ac` wrong, and so we just got no builds
supporting ACLs.
Also, it needs to be more precise because Darwin puts other stuff in
that same header, evidently.
`configureFlags` only included `--with-boost` on Linux, which makes
local builds as outlined in `doc/manual/src/contributing/hacking.md`
fail when performed on macOS.
This was last upgraded in 788008385e, but
the version in Nixpkgs is a now a lot newer. I think the custom was
added to get ahead of Nixpkgs before, and so now that we are in fact
behind, it is no longer needed.
It works with both `ssh://` and `ssh-ng://` now since #9600 (and
`ssh-ng:// didn't work before that).
Also, by making the two tests share code, we nudge ourselves towards
making sure there is feature parity.
I don't love the way this code looks. There are two larger problems:
- eval, build/scratch, destination stores (#5025) should have different
types to reflect the fact that they are used for different purposes
and those purposes correspond to different operations. It should be
impossible to "use the wrong store" in my cases.
- Since drvs can end up in both the eval and build/scratch store, we
should have some sort of union/layered store (not on the file sytem
level, just conceptual level) that allows accessing both. This would
get rid of the ugly "check both" boilerplate in this PR.
Still, it might be better to land this now / soon after minimal cleanup,
so we have a concrete idea of what problem better abstractions are
supposed to solve.
