This is because `mktemp` returns a path like
`/var/folders/z5/fclwwdms3r1gq4k4p3pkvvc00000gn/T/tmp.qDY24l6bIM`,
where `/var` is a symlink to `/private/var`.
Then, we attempt to use that path as a `builder`, which errors because
symlinks are impure or whatever.
Anyways, we can fix this by using `realpath "$(mktemp)"` instead of
`mktemp` directly.
NB: This error doesn't seem to happen when I run the tests through `nix
flake check`. I'm not sure if Nix does something to `TMP` in that case.
It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:
- unit tests depending on building, functional tests don't (e.g. when
we test already-built Nix)
- unit tests can be installed, functional tests cannot
- unit tests neeed extra libraries (GTest, RapidCheck), functional
tests need extra executables (jq).
- unit tests are run by `make check`, functional tests are run by `make
installcheck`
Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.
I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

This keeps hint messages, source location information, and source code
snippets grouped together, while making stack traces shorter (so that
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.
