Motivation for this change

Certain tools, e.g. compilers, are customarily prefixed with the name of their target platform so that multiple builds can be used at once without clobbering each other on the PATH. I was using identifiers named prefix for this purpose, but that conflicts with the standard use of prefix to mean the directory where something is installed. To avoid conflict and confusion, I renamed those to binPrefix.

Things done

No hashes were changed the first time. Then I switched from binPrefix to targetPrefix at @orivej's suggestion. But it was a safe sed, so this still must be fine.

  • Tested using sandboxing (nix.useSandbox on NixOS, or option build-use-sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Fits CONTRIBUTING.md.
