Subject: [PATCH] Stops the pager from blocking at configurePhase (#618)

This is caused by the autoconf check for `nix-store` which is equivalent
to running this:

```
$ nix-store --timeout 123 -q
```

This would open the pager on a 2.1.1 version of nix.

```
$ nix-store --version
nix-store (Nix) 2.1.1
```

Setting `PAGER` to `cat` ensures the pager doesn't block the
configurePhase.

```
$ PAGER=cat nix-store --timeout 123 -q
```
