Description
Apparently, GHC on ARM doesn't support `-threaded`, which makes it impossible to build `cabal-install` without editing the source by hand (see #1129). We should add a configure check for whether `-threaded` is supported.
Contributor guide
Research direction
Start by locating the configure logic that determines compiler support and the place where -threaded is enabled. Check how the project behaves with an ARM GHC, then make the configuration account for whether -threaded is supported. Done means cabal-install can be built without manually editing the source when -threaded is unavailable.
