[BUG] - `cardano-node` `10.2.1` won’t build due to `network` and `old-time`

**Area**
*Other*

**Summary**
`cardano-node` `10.2.1` won’t build on ArchLinux.

**Steps to reproduce**
Use a `PKGBUILD` [like this one](https://pastebin.com/03F8TKPA) to build `cardano-node`. This approach worked fine (at least) until `10.1.4`.

**Expected behavior**
`cardano-node` builds.

**System info (please complete the following information):**
- OS Name: ArchLinux
- OS Version: up-to-date _(Only bad distros have “versions”.)_
- Node version: `10.1.4` builds, `10.2.1` does not.
- CLI version: `10.1.1.0` (irrelevant)

**Screenshots and attachments**
```
Error: cabal: Failed to build network-3.1.4.0 (which is required by
exe:cardano-submit-api from cardano-submit-api-10.1.0, exe:tx-generator from
tx-generator-2.14.2 and others). The failure occurred during the configure
step. The build process terminated with exit code 77
Failed to build old-time-1.1.0.4 (which is required by exe:cardano-submit-api
from cardano-submit-api-10.1.0, exe:cardano-testnet from
cardano-testnet-10.0.0 and others). The failure occurred during the configure
step. The build process terminated with exit code 77

**Additional context**
I’ve tried **all 9 combinations** of GHC version `8.10.7` / `9.6.7` / `9.10.1` with Cabal version `3.8.1.0` / `3.10.3.0` / `3.12.1.0`. All of them fail.
