Description of changes

This commit massively reduces the build latency for glibcLocales by allowing it to build in parallel. This requires passing -j$NIX_BUILD_CORES via the glibc-specific make variable PARALLELMFLAGS.

This commit also fixes a preexisting bug where the glibcLocales package would ignore preBuild and postBuild.

Things done
  • Built on platform(s)
    • x86_64-linux
    • aarch64-linux
    • x86_64-darwin
    • aarch64-darwin
  • For non-Linux: Is sandbox = true set in nix.conf? (See Nix manual)
  • Tested, as applicable:
  • Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
  • Tested basic functionality of all binary files (usually in ./result/bin/)
  • 23.11 Release Notes (or backporting 23.05 Release notes)
    • (Package updates) Added a release notes entry if the change is major or breaking
    • (Module updates) Added a release notes entry if the change is significant
    • (Module addition) Added a release notes entry if adding a new NixOS module
  • Fits CONTRIBUTING.md.
